In recent years there has been rapid progress in electronic circuit design and the main reason for this is the advance in digital techniques. This volume differs from the texts which are available on the market nowadays in two respects. Firstly it covers only analogue electronic circuits and systems; secondly basic electronics is omitted so that appropriate emphasis can be given to the design of the most popular and useful analogue electronic circuits. The following are prerequisites for studying this text:

1. (a) P-N junction diodes: principles of operation both in the forward and reverse mode, characteristic equation, resistance and junction capacitance, Zener diodes.

2. (b) Junction transistors: principle of operation, common-emitter (CE), common-collector (CC) and common-base (CB) configurations, static characteristics, definition of active, cut-off and saturation regions, the concept of load lines and the need for biasing, the transistor as an amplifier.

3. (c) Amplifiers: voltage and current gains (Av and Ai), input and output resistance (Rin and Rout), frequency response concept, the use of the h-parameter model of the transistor for circuit analysis, midband frequencies of the CE, CC and CB configurations and calculation of Av, Ai, Rin and Rout for each case.

4. (d) Field effect transistor: principle of operation, static characteristics, load lines, biasing circuits, use as an amplifier.

5. (e) Positive and negative feedback and their advantages and disadvantages.

6. (f) Operational amplifiers: ideal amplifier, analysis of inverting, noninverting, differential, buffer and summer amplifiers, use of operational amplifiers as integrators and differentiators.
