VDCC based dual-mode quadrature sinusoidal oscillator with outputs at appropriate impedance levels

This article presents a new dual-mode (i.e. both current-mode and voltage-mode) quadrature sinusoidal oscillator using two Voltage Differencing Current Conveyors (VDCCs), two resistors and two capacitors. The proposed configuration use only grounded passive elements and enjoys independent resistor/electronic tuning of both Condition of Oscillation (CO) as well as Frequency of Oscillation (FO). The quadrature current and voltage mode outputs of this circuit are available at appropriate impedance terminals. The behavior of presented oscillator is also examined under non ideal/parasitic conditions. The validity of the proposed configuration has been confirmed by SPICE simulations with TSMC 0.18μm process parameters.
