摘要
在高频域,MOSFET的分布参数对全集成MOSFET-C滤波器的特性有很大影响,本文应用SPICE(Ⅱ)通用模拟电路程序,采用非理想运算放大器单极点电路模型,考虑到MOSFET的寄生电容,对一个六阶切比雪夫低通滤波器全MOSFET-C平衡结构应用传输线模型进行了仿真分析。
At high frequencies, the distributive parameters of MOSFET have great effects on the characteristics of fully integrated MOSFET-C filters. In this paper,full integrated balanced MOSFET -C sixth-order chebyshev lowpass filter is discussed. Its amplitudefrequency and phase-frequency characteristics of output voltage are simulated using the transmission line model by SPICE (Ⅱ) program while MOSFET parasitic Capacitances and Single-pole nonideal op amps model are.considered, and compared with those on ideal cases in which only discreted linear components and ideal op amps are emploied'.Some practical suggesition are proposed.
