Abstract
A new canonical first order voltage-mode all-pass section (VM-APS) employing a single grounded capacitor as the only passive element and two differential voltage current conveyors as the active elements is proposed. The circuit, with its attractive features of resistorless realization, voltage-controlled pole frequency and low impedance voltage output is a novel and unique offering to the field and an addition to the rich literature on the subject. PSPICE simulations are carried out in 0.5 μ CMOS technology to validate the utility of the proposed circuit.
