High-input and low-output impedance voltage-mode all-pass networks

Abstract

In this paper, two new voltage-mode first-order all-pass networks are proposed. Each of proposed networks employs two differential difference current conveyors (DDCCs), one grounded capacitor and one grounded capacitor. No passive component matching conditions are required. The networks offer high-input and low-output impedances; hence it can be directly employed as a subsystem of monolithic circuits. The use of only grounded capacitor and resistor makes the proposed networks ideal for integrated circuit implementation. The characteristics of the proposed all-pass networks are simulated using PSPICE to verify the theory.
