摘要

提出了一种低压低失真数字可编程电流模连续时间滤波器的实现方法。数字可编程技术是基于固有的线性MOST-only电流分割技术。该技术应用于数字可编程电流反射镜(DPCM)的设计。然后利用DPCM设计了一个数字可编程电流模式积分器。作为数字可编程电流模式积分器的应用，设计了一种数字可编程模拟滤波器。选择性和中心频率都可以独立编程。采用0.8 /spl mu/m CMOS工艺参数和3v电源对滤波器进行了仿真。

A low voltage digitally programmable current-mode filter

A technique for a low voltage low distortion digitally programmable current-mode continuous-time filter is proposed. The technique of digitally programmable is based on an inherent linear MOST-only current division technique. This technique is used to design a digitally programmable current mirror (DPCM). Then we used the (DPCM) to design a digitally programmable current mode integrator. As an application for the digitally programmable current mode integrator, a digitally programmable analog filter is designed. Both of selectivity and center frequency can be programmed independently. The filter has been simulated using the parameters of 0.8 /spl mu/m CMOS process, and 3volt power supply.
