This paper proposes a differential switched-capacitor (SC) biquad filter exploiting a hybrid structure. The 1st active core is an operational amplifier (OpAmp) whereas the 2nd is an improved comparator-based circuit (CBC). The advantages of this new structure are justified by the reductions of power and transistor sizes. Optimized in a 65-nm CMOS process, when compared with a typical dual-OpAmp design, the proposed filter saves 19% power and 18% transistor area. The filter clocked at 40 MHz… CONTINUE READING
