Abstract
Systems and methods for improving source-follower-based Sallen-Key architectures are disclosed. In particular, systems and methods for circumventing the non-idealities associated with source-follower-based Sallen-Key biquad filters when used in either baseband signal or radiofrequency paths. The systems and methods disclosed herein present power-efficient, cost-efficient solutions that can be implemented in a reduced area of a circuit.
