CMOS Circuits for Full-custom and Analogue ICs

Abstract

Studying this chapter will enable you

• □ To learn more about static CMOS logic circuits using transistors as switches rather than NAND and NOR gates. The multiplexer and AND-OR-NOT functions become preferred elements in full-custom logic design.

• □ To understand the principles of dynamic CMOS circuits such as domino logic and their problems and advantages.

• □ To become aware of the uses for mixed analogue-digital ASICs and of the semi-custom methods of designing them that are the same as for purely digital ICs.

• □ To appreciate the uses for purely analogue CMOS ICs and, by considering the circuit of a simple CMOS operational amplifier, to find out that analogue design of circuits made entirely of n- and p-channel MOSTs is very similar to bipolar design.
