Abstract :
Low-power CMOS continuous-time Gm-C filter structures are presented. The filters present a compact structure, in which only one current branch for each side of the differential structure is present. In addition the filters exhibit other characteristics as the absence of parasitic poles and CMFB circuit which allows reducing power consumption. A folded version of each filter is also proposed in order to improve the matching.
