This paper presents an efficient design approach for high-frequency analog filters using programmable mixed signal circuits or programmable analog circuits. This approach allows the design of analog filters that works to frequencies higher than 100 KHz, which are not possible using design tools of the PSoC and FPAA vendors. In order to verify the proposed approach, Butterworth band-pass filters were designed considering resonance frequencies of 50 KHz, 100 KHz and 200 KHz.
