Abstract :
This paper describes a project to implement very narrow band filters using switched capacitor techniques. Past attempts to obtain such filters are reviewed and their limitations highlighted. The implementation of a highly reconfigurable 3rd order pseudo-N-path filter (N⩽7), which is based on new circuits that have been developed by the authors, are then described. This filter has been fabricated using MIETEC 2.4 μm CMOS process and measured results are presented and any deviations from die simulation results are explained
