Online Electronics Tutor
Electronics is where circuit analysis meets real devices. Diodes and transistors are non-linear, so the course is built on models and approximations — and knowing which model to use, and when, is most of the challenge.
Sessions work from device behaviour through to working circuits: biasing, small-signal analysis, amplifier design and op-amp circuits, with simulation used to see what the equations predict.

Electronics
Making sense of electronics
The ideas that tend to unlock the rest of the course:
Models and approximations
When is the ideal diode good enough, and when do you need the constant-drop or small-signal model? Choosing the right level of detail is a skill in itself.
DC first, then AC
Most transistor problems split into finding the bias point and then analysing the small-signal circuit. Keeping those steps separate removes a lot of confusion.
Op-amps: the rules and their limits
The ideal op-amp rules make analysis quick, but real behaviour — saturation, bandwidth, offset — explains why lab results sometimes differ.
From analysis to design
Design runs the analysis backwards: choosing component values to meet a gain, bandwidth or bias specification, then checking the result.
Who this tutoring is for
- Undergraduate students taking electronics, analog electronics or electronic devices courses
- Graduate students revisiting analog circuit fundamentals
- Students preparing for electronics exams or resits
- Students who need concept clarification on transistor models and biasing
- Students working on electronics labs or design assignments who want guided problem solving and simulation support
How online sessions work
Live 1-to-1 sessions on Zoom or a similar platform, with screen sharing and a shared digital whiteboard. For Electronics, sessions typically include:
- Device behaviour explained with characteristic curves before jumping into equations
- Circuits analysed step by step: operating point first, then small-signal behaviour
- Worked examples followed by similar problems you solve with guidance
- Simulation used to compare predicted and simulated behaviour
- Design problems approached as a sequence of decisions you can explain
Software & tools

SPICE simulation for analog circuits — DC, AC, transient and parametric analysis.
Circuit Simulation
PSpice
Circuit simulation and analysis for analog and mixed-signal electronics assignments.
Circuit Simulation

FAQ
Electronics tutoring questions
Can you help with both analog and digital electronics?
Yes. Analog topics — diodes, transistors, amplifiers and op-amps — are the most common requests, and digital electronics fundamentals such as CMOS logic are covered too. For digital logic design courses, ask about that subject specifically.
I find transistor biasing and small-signal analysis confusing. Where should we start?
Usually with the device itself: what the characteristic curves mean and why a bias point matters. From there, small-signal analysis becomes a logical next step rather than a set of formulas.
Can you help me understand my electronics lab results?
Yes. Comparing measured results against theory and simulation — and working out where differences come from — is a common and useful focus for a session.
Do you cover electronic circuit design?
Yes. Design guidance covers choosing component values to meet a specification, checking the design with analysis and simulation, and understanding the trade-offs involved.
Can you help with op-amp circuits and active filters?
Yes. Op-amp circuits are a core part of most electronics courses — inverting and non-inverting amplifiers, summing and difference amplifiers, integrators, active filters and oscillators. Sessions cover the ideal analysis first, then the practical limits such as saturation, bandwidth and offset that explain real measurements.
