Dual Input All-Pass Networks Using MO-OTA and its Application

This paper presents a realization of grounded passive elements first order all-pass networks using a multiple-output operational transconductance amplifier (MO-OTA) and three grounded passive elements. The proposed circuit is operated in current-mode for the good benefit as well as high output impedance and cascadability. Therefore, it can be directly employed as a subsystem of monolithic circuit without additional matching circuits. Furthermore, a new quadrature oscillator is presented as an application for confirmed the theory and realistic practically. The PSpice simulation results verifying of theoretical are also included.
