This paper describes the design of a CMOS IC AM demodulator.Design details of the monolithic implementation ofa highly accurate synchronous rectifier in a standard 0.35 µmCMOS process on a ±2.5 V voltage supply are presented.The derived circuit implements an envelope detector with a ±1.5 V output swing on a 15 pF load. Small distortion(THD = .60 dB) and low noise (SNR = 84.7 dB) aresome attractive features of the proposed design.
