摘要

本文描述了一种模拟离散时间均衡器，它使用开关电容(SC)滤波，能够实现比使用传统运放技术更高的速度。该方法采用并行性和信号通路中开环电路的独占性。传统的SC滤波器需要具有高质量电容器的技术来创建准确的比率。该方法消除了信号路径中的高质量电容器，并且适用于数字CMOS工艺。

A 200 MHz 9-tap analog equalizer for magnetic disk read channels in 0.6 /spl mu/m CMOS

This paper describes an analog discrete-time equalizer that uses switched-capacitor (SC) filtering capable of achieving speeds higher than can otherwise be attained using conventional opamp techniques. The approach employs parallelism and exclusive use of open-loop circuitry in the signal path. Conventional SC filters require technologies with high-quality capacitors to create accurate ratios. The approach eliminates high-quality capacitors in the signal path and is amenable to digital CMOS processes.
