Abstract :
This paper describes an analog CMOS circuit for NMT-450 and NMT-900 mobile radio base station signal processing. The circuit includes receive and transmit audio filters, a deviation limiter (AGC and hardlimiter) and two level detectors, all implemented with switching capacitor technology. Measurement results show that strict performance requirements for SNR and filter responses are met regardless of the great number of successive SC-stages.
