Realization and Simulation of Band-Pass Filter Based on MCDI

  • 摘要: 該文提出了利用低電壓多輸出端電流模式全差分積分器(MCDI)設(shè)計(jì)實(shí)現(xiàn)連續(xù)時(shí)間電流模式濾波器的方法.分析并模擬了MCDI及所提出的濾波器的特性,應(yīng)用3.3V,0.5m,CMOS工藝參數(shù)仿真得到的二階帶通濾波器功耗僅為0.6mW左右,且其中心頻率可在很寬的范圍內(nèi)調(diào)控.此外,這種濾波器還具有結(jié)構(gòu)簡(jiǎn)單、對(duì)稱性好、失真小等優(yōu)點(diǎn),適于全集成.
    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.
