Abstract
This study presents a novel high-input impedance voltage-mode differential difference current conveyor transconductance amplifier (DDCCTA)-based universal filter with a single input and five outputs. The proposed configuration uses two DDCCTAs, two grounded capacitors and two grounded resistors. It simultaneously provides voltage-mode lowpass, bandpass, highpass, bandstop and allpass filtering responses, without passive component-matching conditions or restrictions on input signals. The proposed circuit offers high-input impedance and low active and passive sensitivities, and uses only grounded capacitors and resistors.
