Abstract

Abstract

A new single-amplifier switcbed-cap acitor filter using unity-gain amplifier is presented. When used for the relation of high Q bandpass characteristic, the circuit can obtain much less capacitor spread, and its capacitor spread, compared with other circuits given by literatures, is reduced significantly.
