An Efficient Design Approach for High-Frequency Analog Filters Using PSoCs or FPAAs

This paper presents an efficient design approach forhigh-frequency analog filters using programmablemixed signal circuits or programmable analog circuits.This approach allows the design of analog filters thatworks to frequencies higher than 100 KHz, which arenot possible using design tools of the PSoC and FPAAvendors. In order to verify the proposed approach,Butterworth band-pass filters were designedconsidering resonance frequencies of 50 KHz, 100KHz and 200 KHz.
