Multi-phase sinusoidal oscillators using dual output CCIIs

Two voltage-mode multi-phase sinusoidal oscillators are realized in this paper using dual output second generation current conveyors as active elements and with some passive elements. The topology of proposed oscillator-I is a non-inverting band-pass filter and a unity gain feedback circuit. The proposed oscillator-II realizes a voltage mode oscillator and generates eight phases of sinusoidal output having equal magnitudes. PSPICE simulation results confirm the theory.
