Quadrature oscillator using grounded components with current and voltage outputs

This study proposes new third-order quadrature oscillator that provides several voltage and current outputs simultaneously. The circuit uses differential voltage current conveyors and grounded components, enjoys non-interactive frequency control and can be made resistor-less by using voltage-controlled differential voltage current conveyors. Non-ideal study and parasitic effects are also considered and their effects are discussed. The proposed theory is verified through PSPICE by good results.
