This unit deals with a broad and essential range of topics in analogue electronics at an intermediate level. It covers the design of circuits using MOSFET and BJT devices, the effects of feedback, the design of high power amplifiers, and the operation of oscillator circuits.
Elements:
Bipolar Junction Transistors (BJT): BJT Operation, npn and pnp transistors in active mode, analysis of transistor circuit at DC, BJT as an amplifier, small signal equivalent circuit model (the hybrid-pi model, the T model and graphical analysis), BJT discrete circuit design, basic BJT amplifier configurations.
MOS Field Effect Transistors (MOSFET): MOSFET as an amplifier, small signal model, MOSFET discrete circuit design, single stage MOSFET amplifiers, multi-stage amplifiers (differential pair current mirror and cascode).
Feedback: Open and closed loop gain, negative feedback (effect on gain and bandwidth), basic feedback topologies (voltage, current, transconductance and transresistance), analysis of gain, input and output resistance of series-shunt, series-series, shunt-shunt and shunt-series feedback amplifiers.
Output and Power Amplifiers: Classification of output stages, class A, B and AB output stages, biasing analysis of class AB stage.
Oscillators: Principles of sinusoidal oscillators, RC oscillator circuits (Wien-Bridge and Phase shift oscillators), LC tuned oscillator (Colpitts).
On successful completion of this unit, students should be able to:
Teaching will be delivered through a combination of synchronous and asynchronous sessions, including lectures, practical activities supported by drop-in sessions, problem sheets and self-directed exercises.
