Abstract
This paper presents a new third-order quadrature oscillator using operational transresistance amplifiers as active elements. The proposed circuit provides high precision of the frequency of oscillation. The frequency of oscillation can be controlled using a single passive component and the condition of oscillation can be controlled orthogonally by setting the circuit components. Also two quadrature voltage output terminals possess low impedance level which can be directly connected to the load. Simulation results verifying the theoretical analysis are also included.
