In this paper, we will present a new voltage-mode first-order filter circuit. This circuit using one differential voltage current conveyor (DVCC), one capacitor and two resistors. It can realize first-order filter functions which are lowpass and allpass responses. This filter have some characteristic, like: use less active component and passive component, grounded capacitor, no impedance matching required when used as lowpass filter. We use HSPICE and MATLAB to simulate this filter circuit. The results are close to theoretical predictions.
