Realization and Simulation of Band-Pass Filter Based on MCDI
多输出端电流模式全差分积分器实现带通滤波器的方法及仿真

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.
