Abstract
The present invention addresses a need for reducing the power consumption in a baseband filter used in a front-end wireless receiver while providing the necessary linearity. In particular, relatively high linearity can be obtained with lower power consumption than has heretofore been the case. This is achieved in embodiments of the invention using an optimized single-branch fully differential structure which operates as a 'composite' source-follower (when using CMOS devices) with an ideal unitary dc gain. A positive feedback internal to the source follower allows one to synthesize two complex-poles.
