A Novel Pseudo-Differential Integer/Fractional-Order Voltage-Mode All-Pass Filter

The paper presents the first- (integer) and fractional-order case studies of a novel pseudo-differential (P-D) voltage-mode all-pass filter (APF) employing a single differential voltage current conveyor (DVCC), one resistor, and a single grounded capacitor. The proposed filter brings significant reduction of complexity in comparison to available fully-differential or P-D filter topologies. Moreover, it was also shown that fractional-order capacitor can be used for gain response compensation of the proposed APF. The theoretical results of 0.8th and 1st-order APF were verified by Cadence IC6 Spectre simulations using new structure of DVCC via TSMC 0.18 µm CMOS process parameters supplied with ±0.9 V voltages.
