Caseaded Biquad SCF의 구현에 관한 연구

A Study on the Realization of Cascaded Biquad SCF

Prototype Switched Capacitor 4th order Low pass and Band Pass Filters were Realized and tested. Their capacitor values were determined by using automatic SCF design tool. Each filter was designed to operate in voiceband frequency, and practical solutions to improve its frequency characteristics were given. Experimental results show the validity of automatic SCF design program. Simulation and experimental results were fully compared and optimum design conditions were summarized.
