Abstract :
The proposed circuit improves the frequency response, power dissipation and supply range of the KHN biquadratic circuit. It uses a minimum number of Operational Transconductance Amplifiers (OTAs) to achieve the same. The various parameters namely center frequency, dc gain, Bandwidth, Power Dissipation and Quality factor are all electronically tunable. Simulations are included to verify the analysis.
