Abstract
A realization of the quadrature sinusoidal oscillator with the employment of current differencing buffered amplifiers (CDBAs) as active components is proposed. The proposed oscillator circuit is composed of two CDBAs, three resistors, and three capacitors. Outputs of two sinusoidal with 90° phase difference are available from the configuration. The oscillation condition and the oscillation frequency (ω0) of the proposed oscillator can also be orthogonally tuned. Experimental and simulation results obtained using the commercial available AD844 ICs are given to confirm the theoretical analysis.
