Abstract

A novel tuning technique which improves the performances of an RF differential bandpass filter based on simulated inductors is presented. Gain enhancement techniques are applied to reduce the inductor losses by using an extra differential negative resistance. The proposed method is sufficiently general to be applied to other active filters topologies based on active inductors as well and is intended to be used for CMOS multi-standard filters design.
