Design and Simulation of Switched Capacitor Filter for Speed Change Parameter Converter

摘要：

　　In this paper,we design a high-order switched capacitor filter for rapid change parameter converter.This design uses a structure which consists of three biquads filter sub-units.The design is a 6th-order SC elliptic low-pass filter,and the sample frequency is 250 kHz.By the MATLAB Simulink simulation,the system can meet the design requirements in the time domain.In this paper,the 6th-order switched capacitor elliptic low-pass filter was implemented under 0.5 um CMOS process and simulated in Cadence.The final simulation results show that the pass-band cutoff frequency is 10 kHz,and the maximum pass-band ripple is about 0.106 dB.The stop-band cutoff frequency is 20 kHz,and the minimum stop-band attenuation is 74.78 dB.
