This paper reports a comprehensive solution for the problem of test and diagnosis of OTA based analog circuits. Based on the parametric deviation of circuit components, a test and diagnosis methodology is proposed. Compressed signature generated out of multiple performance parameters has resulted in significant enhancement in fault diagnosing capability.(More)
— This paper proposes a signal processing methodology of communication system and realized that circuits using operational transconductance amplifier (OTA). Two important classes of communication circuit, delta modulator and compander have been designed using that procedure. In the first implementation coded pulse modulation system is demonstrated which(More)
This paper presents a novel programmable biquadratic filter structure using a network of operational transconductance amplifier(OTA). A new hierarchical design methodology of programmable higher order analog filter using the proposed biquadratic function as the basic building block has been discussed. The proposed biquadratic structure offers multifunction(More)
