Abstract :
A low-power CMOS continuous-time biquad cell is presented. The cell presents a compact structure, in which only one current branch for each side of the differential structure is present. In addition the filter exhibits other characteristics which allows reduced power consumption because of the absence of parasitic poles and CMFB circuit.
