Abstract :
A novel tuning principle for RF CMOS bandpass filter with simulated inductor which allows independent frequency and Q factor tuning is presented. The filter is an improved version of a previously reported topology and makes use of an extra negative conductance in order to implement independent tuning. The proposed method seems to have a sufficient degree of generality in order to be extended to other active filters topologies as well.
