摘要

提出了一种应用于视频频段的基于三极管的五阶椭圆低通连续时间滤波器。该滤波器采用标准的2μm CMOS技术制造，采用简单的寄生极补偿方案实现7 MHz截止频率。提出了一种新的跨导体偏置策略，可以在十年内实现跨导体的调谐。

A 2μm CMOS 5th Order Low-pass Continuous-Time Filter for Video-Frequency Applications

A 5th order elliptic low-pass continuous-time filter based on triode transconductors for applications in the video frequency range is presented. Fabricated in a standard 2μm CMOS technology, the filter achieves a 7 MHz cut-off frequency using a simple parasitic pole compensation scheme. A new transconductor biasing strategy is also presented, which allows the tuning of the transconductance over a decade.
