EEE3308C: Electronic Circuits 1

Course Description

EEE3308C Electronic Circuits 1 is where an electrical engineering student stops analysing circuits made of resistors, capacitors and ideal sources and starts working with the nonlinear, three-terminal devices — diodes, bipolar transistors and MOSFETs — that make electronics do anything interesting.

The statewide inventory records the course at four institutions, including Florida Polytechnic University, the University of Florida, the University of North Florida and the University of West Florida.

UWF's entry describes "fundamentals of analog electronic circuits and systems", places the course in the Department of Electrical and Computer Engineering, and carries two conditions worth reading carefully:

• Prerequisite: (EGN 3204 OR EGM 3344) AND ((EEE 3308L* AND EEL 3111)) — a numerical methods or engineering analysis course, plus circuits, plus the concurrent laboratory.
• ⚠⚠ "A grade of 'C' or better is required in the prerequisites." Passing the prerequisite is not sufficient — a D in circuits blocks this course.
• ⚠ "Credit may not be received in both EEE 3308 and EEL 3304." An exclusion; see Special Information.

Why this course is the gate in an electrical engineering degree. Circuit analysis teaches linear systems, where superposition works and every element obeys a proportional law. ⚠ Electronics is where that stops being true. A diode's current is exponential in its voltage; a transistor's behaviour depends on which region it is operating in; and the engineering method that makes any of it tractable is to establish a DC operating point and then analyse small signal variations around it as if the device were linear.

⚠⚠ That two-step — bias the device, then linearise around the bias — is the single most important idea in the course, and students who do not internalise it spend the rest of the term confused about which model to use when. DC analysis and AC small-signal analysis are separate calculations on the same circuit, and mixing them is the characteristic error.

The arc of the material. Semiconductor basics and the pn junction; diodes — models, rectifiers, clippers, clampers, Zener regulators; bipolar junction transistors — operation, biasing, the common-emitter, common-base and common-collector configurations, small-signal models; MOSFETs — operation, biasing, the three amplifier configurations, and ⚠ the CMOS inverter, which is the bridge to digital electronics and to every processor ever built; then frequency response, multistage amplifiers, differential pairs, and an introduction to operational amplifiers as circuits rather than as ideal blocks.

The laboratory is where the abstraction gets tested. ⚠ The experience the course is built to deliver is a circuit that is analytically correct and does not work — because of a bias point that drifted with temperature, a device whose beta is nothing like the datasheet's typical value, a breadboard's parasitic capacitance, or a supply rail that sagged. Learning that the datasheet gives a range and the design must tolerate the whole range is the point.

Resources & Tools

• Sedra and Smith, Microelectronic Circuits — ⚠ the dominant text in this course worldwide, comprehensive and demanding; Neamen, Microelectronics: Circuit Analysis and Design — often preferred as more approachable for a first course; Razavi, Fundamentals of Microelectronics — ⚠ the best at explaining why a circuit is built the way it is, and worth reading alongside whichever is assigned.
• ⚠⚠ Free and genuinely excellent: All About Circuits and Electronics Tutorials for concept explanations, and Khan Academy's electrical engineering unit. Razavi's own lecture videos are free on YouTube and are among the best available for this material.
• Simulation, and you should install one: LTspice — ⚠ free, unrestricted, industry-standard, and the one to learn; ngspice; Falstad's circuit simulator, which runs in a browser and is unmatched for building intuition quickly; Multisim and PSpice where the department provides them; TINA-TI from Texas Instruments.
• Laboratory instruments you will use: DC power supply, function generator, oscilloscope — ⚠ learn to drive the oscilloscope properly in the first two weeks; it is the instrument that separates students who can troubleshoot from students who cannot — digital multimeter, and increasingly USB instruments such as the Analog Discovery, which many students buy for home use.
• Datasheets are primary sources in this course: the 2N3904 and 2N2222 BJTs, the 1N4148 and 1N400x diodes, the 2N7000 MOSFET and the 741 and LM358 op-amps recur everywhere. ⚠ Read one properly, including the tolerance columns — the difference between minimum, typical and maximum beta is the whole reason bias stabilisation exists.
• Suppliers: Digi-Key, Mouser, Jameco and Adafruit. ⚠ A modest personal component kit and a breadboard pays for itself — being able to try something at home rather than only in the scheduled lab session changes how much you learn.
• Professional: IEEE and its student branch; the NCEES FE Electrical and Computer reference handbook, which is free and covers this material.

Career Pathways

• Electrical engineers (SOC 17-2071) and electronics engineers (SOC 17-2072) — ⚠ this course is core to both, and it is examined on the FE Electrical and Computer exam.
• Analog and mixed-signal design engineers (SOC 17-2072) — ⚠⚠ a genuinely scarce specialisation. Digital design has been heavily automated; analog design has resisted automation and analog designers remain in short supply and are paid accordingly. This course is the entry point, and students who enjoy it should know that.
• Hardware and embedded systems engineers (SOC 17-2061, 17-2072).
• RF and communications engineers (SOC 17-2072) — the frequency-response material leads here.
• Power electronics engineers (SOC 17-2071) — ⚠ growing demand from electric vehicles, solar and grid storage, all significant in Florida.
• Semiconductor process and device engineers (SOC 17-2199, 17-2112).
• Test and applications engineers (SOC 17-2072, 17-3023).
• Aerospace and defence electronics (SOC 17-2011, 17-2072) — ⚠⚠ Florida's strongest electronics employment sector: L3Harris in Melbourne and Palm Bay, Lockheed Martin in Orlando, Northrop Grumman in Melbourne and St. Augustine, Raytheon, Siemens Energy in Orlando, and the Space Coast launch and payload industry. Most require or strongly prefer US citizenship for clearance-eligible roles.
• Medical device engineering (SOC 17-2031) — a growing Florida sector.
• Graduate study (SOC 25-1032) — microelectronics, photonics, integrated circuit design.

⚠ Practical note: the laboratory half is what employers interview on. Being able to say what you built, how it failed and how you diagnosed it is worth more in an interview than a transcript grade — keep your lab work.

Special Information

⚠⚠ Three enrolment conditions at UWF

1. Register for both EEE 3308 and EEE 3308L. Each lists the other as a concurrent prerequisite; ⚠ neither can be taken alone, and the pair is 4 credits.
2. ⚠⚠ A grade of C or better is required in the prerequisites. The prerequisites are (EGN 3204 OR EGM 3344) — numerical methods or engineering analysis — AND EEL 3111, circuits. A D in circuits does not clear the gate, and this catches students who passed and moved on. Check your grade, not just your transcript credit.
3. ⚠ Credit may not be received in both EEE 3308 and EEL 3304. These are alternative routes to the same requirement — EEL 3304 is a common electronics number at other Florida institutions. A transfer student arriving with EEL 3304 may not be able to take this course for credit, and taking both wastes a course. Check before registering.

Prerequisites — what is listed and what is assumed

• EEL 3111 (circuits) is the load-bearing prerequisite. ⚠ Everything in this course is Kirchhoff's laws applied to nonlinear devices, and a student shaky on node and mesh analysis, Thevenin equivalents or phasors will be learning two things at once.
• EGN 3204 or EGM 3344 — numerical methods / engineering analysis, supporting the frequency-response and simulation work.
• ⚠ Unlisted but decisive: differential equations and comfort with complex numbers and Laplace-domain thinking, for frequency response; and enough physics to be comfortable with the idea of charge carriers.
• ⚠⚠ The most useful preparation is not a course. Students who have built things — hobby electronics, Arduino projects, repairs, amateur radio — find this course dramatically easier, because the laboratory half rewards physical intuition that lectures cannot supply. If you have never built a circuit outside a lab session, build one before the term starts.

Course format and workload

3 credits, 60 contact hours in the integrated C form. In the split form, 3 credits / 45 hours lecture plus 1 credit / 30–45 hours laboratory — 4 credits total.

⚠⚠ Budget 10–14 hours per week outside class. This is among the hardest courses in an electrical engineering degree, and it is frequently where students discover whether the major is for them. Two things drive the load: the problem sets are long, and the laboratory work is unbounded — a circuit that does not work takes as long as it takes.

Assessment typically includes two or three examinations, weekly or biweekly problem sets, laboratory reports, SPICE assignments, and often a design project.

⚠ Where students actually struggle

• ⚠⚠ Confusing DC and AC analysis. The characteristic error, and it produces answers that are wrong by orders of magnitude. Do the bias analysis completely, then draw the small-signal equivalent circuit as a separate drawing. Students who try to do both on one schematic get lost.
• Deciding which device model to use. Ideal diode, constant-drop, or small-signal; hybrid-pi or T-model. ⚠ The model is chosen for the question being asked, and that judgement is itself a skill the course is teaching.
• Small-signal equivalent circuits. Drawing them correctly — capacitors shorted, DC supplies grounded, device replaced by its model — is mechanical and worth drilling until it is automatic.
• Frequency response and Bode plots. Identifying which capacitor causes which pole. The method is systematic; the practice is what makes it fast.
• ⚠⚠ Laboratory troubleshooting, which almost nobody arrives able to do. The productive habit is to measure the DC bias point first — if the operating point is wrong, nothing downstream will make sense. Then check the signal at each node in order. Do not rebuild the circuit hoping it works the second time.
• Reconciling simulation with measurement. ⚠ They will differ, and explaining the difference is the assignment — component tolerance, parasitic capacitance, loading by the oscilloscope probe, and the fact that SPICE models are approximations too.

⚠ Laboratory safety and equipment care

• The voltages in this laboratory are generally low and the currents are not always trivial — a shorted supply can heat a component to the point of burning skin, and electrolytic capacitors connected backwards can vent violently. Check polarity before applying power.
• Power down before rewiring. Every time.
• ⚠ Static discharge destroys MOSFETs invisibly — the device tests fine and fails intermittently later. Handle them by the package and use the grounding provisions the lab supplies.
• Where a bench supply exceeds 30 V or a project involves mains, treat it as a different hazard class and follow the lab's rules exactly.

Articulation and transfer

⚠ The suffix and the credit count are the transfer issue. EEE3308C (3 credits, integrated) and EEE3308 + EEE3308L (4 credits, split) carry the same subject under different identifiers, and SCNS equivalency does not cross the suffix automatically.

⚠⚠ Compounding it, the exclusion above shows the subject also lives under a different NUMBER at some institutions — EEL 3304. So a transfer evaluator has three shapes to reconcile: the integrated C, the split pair, and a different number entirely. Keep the syllabus and the lab manual.

Prefix note. EEE is electrical engineering electronics; EEL general electrical engineering; EGN general engineering; CDA computer design and architecture. ⚠ Electronics is numbered under both EEE and EEL in Florida and the split is departmental convention rather than a content difference. Search by subject rather than prefix.

This is an upper-division course, normally junior year, and Florida College System institutions do not offer it — an A.A. transfer student meets it after transfer. ⚠ Engineering technology programmes teach an electronics course that is NOT equivalent for an ABET-accredited engineering degree; the articulation is asymmetric, as it is with engineering technology calculus. Check with the receiving department before assuming it substitutes.

AI Integration

Where AI assistance genuinely helps here:

• Explaining a concept a second way. Why bias stabilisation works, what the Early effect is, why the common-base configuration has low input impedance — these are places a different explanation frequently lands.
• Checking algebra in a long small-signal derivation, after you have set it up.
• SPICE netlist syntax and simulation setup, which is fiddly and is not what the course is assessing.
• Interpreting a datasheet parameter you have not met before.
• Structuring a laboratory report and improving its technical writing.

⚠⚠ Where it fails, and this course is a particularly clear case:

• ⚠⚠ Circuit analysis arithmetic and, more importantly, model selection. Models produce confident numeric answers for amplifier gain and bias points that are frequently wrong — usually because the wrong device model or the wrong operating region was assumed. ⚠ The failure is invisible: the answer has the right units and a plausible magnitude. Check it in SPICE, which is free and definitive.
• Fabricated device parameters. Invented datasheet values for real part numbers. Get the datasheet.
• Design that ignores tolerance. ⚠⚠ A generated design will use typical values. Real transistors have betas varying by a factor of three across a production lot, and a bias network that works at typical beta and fails at minimum is exactly the design error this course exists to teach you to avoid. The whole point of emitter degeneration is insensitivity to a parameter the model quietly treats as fixed.
• Troubleshooting. ⚠ A model cannot see your breadboard. It cannot know that a lead is not seated, that a probe is loading the node, or that the supply is current-limiting. Physical debugging is measurement plus reasoning, and it is the most employable skill in this course.

Where AI genuinely intersects this field — and the connection is closer than students expect. ⚠ Every AI accelerator is analog and digital electronics. The demand for machine learning has driven a semiconductor investment cycle, and the bottlenecks are power delivery, thermal management, memory bandwidth and signal integrity — all electronics problems. Meanwhile analog in-memory computing and neuromorphic hardware are active research areas that use analog device physics directly to perform computation.

⚠ In the other direction, machine learning is being applied to analog circuit design and to layout optimisation, with real but limited results — which is one reason analog designers remain in demand: the problem has resisted automation for forty years.

Academic integrity, with an engineering note. Follow the course policy, which for problem sets and lab reports is normally specific. Submitting generated work as your own violates every Florida institution's policy. ⚠ Beyond the grade: this material is examined on the FE exam, in technical interviews, and in the first job — and it is the foundation for every electronics course that follows. The gap arrives quickly and visibly.
