Active Only Realization of Image Reject Complex Filter

Abstract

A new complex-filter which offers substantial area reduction is presented. According to this topology, the real-active only integrator is used for implementing the first order image reject filter. We have also discussed the design of a new area effective second order complex filter using lossy integrator building blocks. Using SPECTRE simulation tool, we have also justified the feasibility of the proposed circuit.
