Abstract
An approach to implement low-voltage continuous time filters using simple OTAs and Miller integrators is presented. The technique allows direct translation of system block diagram into a CMOS circuit implementation using differential pairs as OTAs and gain stages as Miller Integrators. A efficient compensation technique to cancel excess phase in Miller integrators is discussed. A high frequency compensated CMOS universal filter structure is discussed and experimentally verified
