摘要

本文提出了一种用于二进制输入信号处理的开关电容(SC)结构。该结构对于实现有限脉冲响应(FIR)滤波器特别有用。设计了一种采用11个电容的23阶升余弦(RC)滤波器。采用0.8 /spl mu/m模拟CMOS工艺对该滤波器进行了仿真。Hspice结果表明了所提出的设计方法的可行性。

SC implementation of FIR filters for digital communication systems

In this paper a Switched-Capacitor (SC) architecture for the processing of binary input signals is presented. The architecture is especially useful for the realization of Finite Impulse Response (FIR) filters. A 23-th order Raised-Cosine (RC) filter employing 11 capacitors is designed. The filter has been simulated using a 0.8 /spl mu/m analog CMOS process. Hspice results have shown the feasibility of the proposed design technique.
