摘      要：Two novel switched-capacitor(SC)bandpass filters using a single operational am-plifier(op amp)are *** designs for minimizing capacitor spread are also ***-bandwidth product(GB)effects of op amps on the proposed SC circuits are taken *** with the proposed circuits and the circuits given by the literatureshow that the new circuits require less chip area in monolithic integration and are less sensitiveto the GB effects.
