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。 Based on the analysis of low voltage operation of traditional CMOS inverters, this paper presents a novel CMOS high-pass filter whose cut-off frequency can be continuously adjusted by adjusting the channel admittance of a CMOS transistor operating in a subthreshold region . The circuit that this text puts forward is simple in structure, the power consumption is very low, can totally integrate. The results of the design verification by PSPICE is correct.
