Abstract :
The performance characteristics of a three-amplifier biquad current due to W.B. Mikhael and B.R. Battacharyya (1975) are analyzed. The effects of the finite gain-bandwidth (GB) product of the op amps used in the circuit are included. An optimum design method for this filter circuit that will minimize the effects of the GB product is presented
