In this paper, a new current-mode universal filter based on Current Differencing Transconductance Amplifier (CDTA) is presented. The proposed circuit uses one CDTA, two grounded capacitors and two resistors. The filter has single input and three outputs which realize low-pass, band-pass and high-pass filter responses from the same circuit configuration. The proposed circuit can also be used to realize an all pass and band-reject current-mode filters. The PSPICE simulation results are shown. The simulated results agree with the theoretical analysis.
