Novel current-mode all-pass filter with minimum component count

Abstract — In this paper, two novel first order current-mode all-pass filters are proposed using a resistor and a grounded capacitor along with a mult i-output dual-X second-generation current conveyor (MO-DXCCII). There is no element matching restriction. Both the circuits exh ibit low input and high output impedance, which is a desirab le feature for current-mode circuits. The proposed circuits are simulated using SPICE simulation program to confirm the theory. Index Terms — Analog signal processing, DXCCII
