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.
