Analogue circuits

Abstract

ELECTRONIC circuits, particularly ICs, are classified as analogue or as digital. Analogue integrated circuits of all kinds are becoming more and more diverse, but the most popular analogue IC is the operational amplifier and its close relation the comparator, both of which are discussed in Chapter 3. Of the remainder the most numerous ICs are analogue-to-digital (and digital-to-analogue) converters and voltage regulators. All of these types together account for about 80% of IC usage. In the next sections we shall look at some other classes of circuit to see how they have been adapted to IC technology. One of the most difficult to adapt has been filters, because they normally contain inductors and capacitors, although only the latter are absolutely essential.
