On Frequency and Quality FactorIndependent Tuning Possibilities for RF Band-pass Filters with Simulated Inductors

Abstract. A novel tuning principle for RF CMOS band-pass filter with simulated inductor allowing independent frequency and Q factor tuning is presented. The method makes use of a supplementary negative conductance and is sufficiently general to be applied to other active filters topologies as well. The proposed solution is intended to be used in the design of active multi-standard CMOS RF filters for mobile and network systems.
