摘要

本文介绍了一种用于NMT-450和NMT-900移动无线基站信号处理的模拟CMOS电路。该电路包括接收和发送音频滤波器，一个偏差限制器(AGC和硬限制器)和两个电平检测器，全部采用开关电容技术实现。测量结果表明，无论连续SC级的数量多，都能满足对信噪比和滤波器响应的严格性能要求。

An Analog CMOS Circuit for Mobile Radio Base Station Signal Processing

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.
