A new mixed-mode quadrature oscillator circuit using two multi-output current controlled conveyors (MOCCCIIs) and two grounded capacitors is presented. In the proposed circuit, four quadrature current-mode signals are available at high impedance nodes. The oscillation conditions and oscillation frequencies are orthogonally (or independently) controllable. Further, two voltage-mode signals in phase quadrature can also be simultaneously obtained from the circuit. The use of only grounded capacitors makes the proposed circuit ideal for integrated circuit implementation. Results of PSPICE simulation confirm the proposed theory.
