Voltage-and Current-Modes Sinusoidal Oscillator Using a Single Differential Voltage Current

This paper presents a new sinusoidal oscillator using a single differential voltage current conveyor (DVCC) and five passive components. The proposed oscillator concurrently provides voltage output and current output, and can independently control the oscillation condition without affecting oscillation frequency. The proposed circuit has a dual-mode (i. e., voltage and current modes) operation property, including low active and passive sensitivities, as well as a desirable total harmonic distortion (THD). This study first introduces the DVCC device and the proposed oscillator circuit, and thereafter presents the non-ideal effects and the results of the sensitivity study of the proposed circuit. This study conducted simulations for the proposed circuit using HSPICE, and used commercial ICs and discrete components for circuit implementation and testing to verify its feasibility. Computer simulations and experimental results confirmed the validity of theoretical analysis.
