Abstract
In this paper, a single-input five-outputs (SIFO) biquadratic active voltage filter with high-input impedance is proposed. The proposed circuit is based on using differential difference current conveyor transconductance amplifier (DDCCTA). It employs three DDCCTAs as active element together with one grounded resistors and two grounded capacitors as passive elements. The circuit also has the advantage of high-input impedance terminal, the simultaneous realization of lowpass, bandpass, highpass, bandstop and allpass voltage responses from the same topology and low sensitivity performance. PSPICE simulation results are included using 0.5 μm MIETEC CMOS technology parameters.
