Resistor Controlled Voltage-Mode Eight-Phase Sinusoidal Oscillator Using MOCCIs

A simple scheme is given for the realization of a voltage mode three-output sinusoidal oscillator (VMTOSO). Using this scheme a negative type second generation current conveyor, [CCII(-)]-based VMTOSO is realized. The [CCII(-)]-based VMTOSO is then transformed into a multioutput current conveyor [MOCCII]-based voltage mode eight-phase sinusoidal oscillator (VMEPSO) by replacing all the CCII(-) by MOCCIIs and some additional grounded passive components. The proposed circuit enjoys attractive features such as independent control of frequency and condition of oscillation, almost equal magnitude and equally spaced in phase voltage outputs, grounded passive components and low sensitivity figures. The use of grounded passive components makes the circuit suitable for IC implementation. The proposed oscillator circuit is designed and verified using Pspice simulation.
