Electronics for Physicists
This course, of 30 lectures, is given to Physics undergraduates in the
3rd and 4th years. Its objective is to provide a systematic introduction
to the world of electronics to physicists. The emphasis is on the basic
concepts of analogue electronics. The analysis and understanding of simple
circuits is based on a black box, functional approach, with extensive use
of simplified equivalent circuits.
1. From DC network analysis to operational amplifiers
Ideal and real voltage and current sources; Kirchhof’s circuit laws; Thevenin
and Norton equivalent circuits; Two-port networks; Input and output impedances;
Controlled voltage and current sources; Amplifiers; Negative feedback:
concept, configurations and analysis; The ideal operational amplifier and
2. Time-dependent signals and circuits
Time-dependent sources; "Energy-storage" components and differential relationships
between voltages and currents; Laplace transforms and applications to the
concept of generalised impedances; Passive and active filters; Bode diagrams
of frequency dependent circuits; Positive feedback: oscillators; The frequency
response of op-amp circuits.
3. Diode and transistor circuits
Diodes and applications; Transistors: basics, biasing, and equivalent circuits;
Single transistor circuits and differential pairs; Current mirrors, active
loads; Op-amps: departures from ideal, consequences; Basic transistor switch;
Basic digital circuits.
4. More complex electronics circuits
Construction of operational amplifiers; Digital-to-analogue and analogue-to-digital
converters; Voltage and current regulators.
