Complementary metal-oxide-semiconductor (CMOS) is a technology for constructing integrated circuits. CMOS technology is used in microprocessors, microcontrollers, static RAM, and other digital logic circuits. CMOS technology is also used for several analogue circuits such as image sensors, data converters, and highly integrated transceivers for many types of communication. This book presents current research data in the study of CMOS technology, including CMOS lithography; the variability and reliability in ultra-scaled CMOS devices; linear and non-linear applications of CMOS DVCC; compact modelling of multi-gate MOSFET; CMOS implementation and application of Differential Voltage Current Conveyor (DVCC); and the feed-through logic for designing high performance arithmetic circuits in CMOS technology.
