Abstract :
In this paper, design methodology of programmable biquad OTA-C filter is presented. Biquadratic structure is realized with OTA, resistor and capacitor. The circuit realizes all types filter i.e. low-pass, high-pass, band-pass, band-reject and all-pass only by configuring the input combinations. All the filter responses are validated with SPICE simulation.
