High-Frequency Analog Filters in Deep-Submicron CMOS Technology

High-frequency analog filters are used in two areas. First, as preprocessing blocks in front of an A/D or as post processing blocks after a D/A. Examples are anti-alias filters for digital TVs, equalizers in digital modems and preconditioning filters in data recording channels (HDD). Second, as building blocks in the front end of a ΣΔ converter. This paper concentrates on submicron CMOS continuous-time filters since increasing system speed requires use of the latest IC technology
