Third Order Quadrature Oscillator Using Two CCIIs and One DVCC with Grounded Passive Components

A new voltage-mode third order quadrature oscillator circuit using two second-generation current conveyors (CCIIs), one differential voltage current conveyor (DVCC), four grounded resistors and three grounded capacitors is presented in this paper. Two voltage-mode signals with 90° phase difference are available in the proposed circuit. The oscillation condition and oscillation frequency are independently controllable through the grounded resistors. The use of all grounded passive components makes the circuit ideal for integration.
