Design and Characterization of a Digitally Tunable Gm-C Filter for Multi-Standard Receivers

This paper presents the design, simulation, prototyping, and measurement results of a digitally tunable fourth order Gm-C low-pass filter (LPF) for multi-standard radio receivers. The LPF cut-off frequency can be tunned by digitally selecting the transconductance of the basic reconfigurable operatio...
