In this study, first CMOS realization of a Current Differencing Transconductance Amplifier (CDTA) is presented. The performance of the circuit is demonstrated using SPICE program. Then, this circuit is applied on a previously reported active filter. Active filter has multiple outputs which are simultaneously realizing lowpass, bandpass and highpass transfer functions.
