Realization and Simulation of Band-Pass Filter Based on MCDI

摘要

摘要: 该文提出了利用低电压多输出端电流模式全差分积分器(MCDI)设计实现连续时间电流模式滤波器的方法.分析并模拟了MCDI及所提出的滤波器的特性,应用3.3V,0.5m,CMOS工艺参数仿真得到的二阶带通滤波器功耗仅为0.6mW左右,且其中心频率可在很宽的范围内调控.此外,这种滤波器还具有结构简单、对称性好、失真小等优点,适于全集成.

Abstract: A methodology to realize continuous-time current-mode filters using low-voltage Multi-output Current-mode Differential Integrator (MCDI) is presented. At first, the char-acteristics of MCDI and the proposed filters which employ MCDI are analyzed and simu-lated. Simulation results not only predict second-order band-pass filter dissipating as little as 0.6mW power or so with 3.3V power supply using 0.5/xm CMOS technology, while the center frequency of which can be tuning in a wide range, but also with the advantages such as simple structure, good symmetry, low harmonic distortion, and suitable for integration.
