摘要
本文基于对传统的ＣＭＯＳ反相器的低电压工作状态的分析，提出了新颖的ＣＭＯＳ高通滤波器，其截止频率可以通过调节工作于亚阈值区的ＣＭＯＳ管的沟道导纳来实现连续可调。本文提出的电路结构简单，功耗极低，可全集成。文中设计结果经ＰＳＰＩＣＥ仿真验证是正确的。
This paper proposes a novel CMOS high pass filter whose cut off frequency can be tuned by tuning the channel transconductance of CMOS transistors which works in weak inversion region, based on the discusses of conventional CMOS inverter. The circuit in this paper have simple structure, low voltage and low power, possibility of totally integrated. The results of design are accurate verified by PSPICE.
