Weeks 3-8 Michaelmas term and weeks 1-3 Lent term. 22 lectures, (16 on AC circuits (TW), 4 on AC power (FU), 2 lectures/week, in Michaelmas term, 3/week in Lent term.
Aims
The aims of the course are to:

Objectives
As specific objectives, by the end of the course students should be able to:
- Ohm's law, ideal voltage and current sources, Thevenin and Norton theorems and Kirchhoff's laws in DC circuit analsys (Lectures 1-2)
- Power is transferred from a source to a load and how any network can be represented by a Thevenin or a Norton source.(Lecture 3).
- Complex numbers in the analysis of AC circuits leading to impedance. Resonance, Q-factor in electronic circuits.(Lectures 4-5).
- Analyse AC circuits including gain, frequency response, and impedances of AC circuits.(Lectures 6).
- Introduce the amplifier model to determine gain, input and output impedance. Bode plots and frequency response (7-8)
- Understand how doped semiconductors can produce p-type and n-type, introduce the p-n junction diode. (Lecture 9)
- Know the principles of operation of the Metal Oxide Semiconductor Field Effect Transistor (MOSFET).(Lecture 10)
- Know how an equivalent circuit for a MOSFET can be used to determine the small-signal performance of the circuits.(Lectures 11-13).
- Introduction to ideal operational amplifiers (Op Amps) and examples of useful circuits (Lectures 14-26).
- The concepts of real, reactive and apparent power, and power factor, power factor correction of AC loads (FU Lectures 1-2)
- The principles of the transformer, and the development and use of its equivalent circuit. (FU Lectures 3-4)

INTEGRATED ELECTRONICS PROJECT (IEP)
The lecture course is run in conjunction with the integrated electronics project (IEP) series of practical exercises. A kitset of components will be provided along with a PicoScope which will allow experiments to be run in parallel with lectures and examples sheets. These will also tie in with LTSpice simulations and experiments performed in the lectures.
