Current-mode quadrature sinusoidal oscillator with current and voltage outputs

A new current-mode quadrature oscillator, which provides both current and voltage outputs simultaneously is proposed. The proposed circuit employs two differential voltage current conveyors, two grounded capacitors and three grounded resistors. The condition oscillator and the frequency oscillation are orthogonally controllable. The proposed circuit can be made electronic control by using voltage-controlled differential voltage current conveyors. Simulation results verifying the theoretical analysis are also included. ©2010 IEEE.
