摘要:
从开关电容滤波器的原理出发 ,通过MATLAB的仿真 ,在时钟频率与中心频率的比值达到一定数值的时候 ,把S域函数进行变换 ,用信号流图的方法设计模拟滤波器 ,从而提高滤波器的精度和可靠性 ,并在 0 .2 5 μm的CMOS电路中实现
Abstract:
The principle of the switch capacitor filter was studied. The transfer of the S domain function was dealt with when the ratio of the clock frequency to the central frequency reached a certain value. The analog filter was designed by adopting the sig nal graph method to improve the precision and the reliability , with the function realized in the CMOS circuit of 0. 25μm.
