Abstract: A current-mode universal biquadratic filter is presented. The architecture has three input terminals, one output terminal using one differential difference current conveyor (DDCC), two grounded capacitors and two resistors. It can realize all standard second-order filter functions, which are, highpass, bandpass, lowpass, notch and allpass responses without changing the circuit topology. The proposed circuit employs only one DDCC that simplifies the circuit configuration.
