A revised guide to the theory and implementation of CMOS analog and digital IC designThe fourth edition of CMOS: Circuit Design, Layout, and Simulation is an updated guide to the practical design of both analog and digital integrated circuits. The author?a noted expert on the topic?offers a contemporary review of a wide range of analogdigital circuit blocks including: phase-locked-loops, delta-sigma sensing circuits, voltagecurrent references, op-amps, the design of data converters, and switching power supplies.
