Abstract :
In this paper a current- and voltage-mode third-order quadrature oscillator circuit using current and voltage conveyors is presented. The features of the new circuit are the oscillation frequency control non-interactive to the condition of oscillation, the use of only grounded passive elements, and the possibility of both quadrature current and voltage outputs. Using the CMOS implementation of the active elements, Spice simulation results are given to verify and demonstrate the performance of the new oscillator.
