Sinusoidal quadrature oscillator using voltage differencing gain amplifiers (VDGAs)

2015 7th International Conference on Information Technology and Electrical Engineering (ICITEE), 2015
An alternative topology of voltage-mode sinusoidal quadrature oscillator based on VDGA (voltage differencing gain amplifier) is proposed. The proposed quadrature oscillator consisting of two VDGAs and two grounded capacitors with the absence of the external passive resistors can generate two sinusoidal output voltages with 90° phase difference.
