Abstract

A novel large input range source-follower based bi-quad filter cell is proposed offering an additional degree of freedom to the position of the poles and zeros. Simulation results of a 4th order fully differential elliptical filter in a 0.13μm CMOS technology confirm a power consumption of 160μA @ 1.2V, an IIP3 of 6.3 dBm and a steepness of 177 db/decade.
