Open publisher page 0 citations

Abstract

A new single input and five output voltage-mode universal biquadraic filter by using differential difference current conveyor(DDCC)was presented. The filter circuit was composed of two plus-type DDCC and three resistors and two grounded capacitors. The filter can simultaneously realize band-stop, highpass, lowpass, bandpass and all-pass filtering responses without extra circuit. It permits orthogonal controllability of the quality factor Q and resonance angular frequencyω and the low active passive sensitivity. PSPICE simulations results demonstrate that the theoretical analysis is correct.
