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.
