Abstract :
A new current-mode biquad filter configuration based on dual output operational transconductance amplifier is presented. Design equations of various filter functions and sensitivity expressions are given. Based on a discrete bipolar transistor realisation and the cascade approach, the measured frequency response results of 4th order lowpass 5.5 MHz Butterworth filter is included
