Abstract

The voltage-mode quadrature sinusoidal oscillator using single voltage differencing tranconductance amplifier (VDTA) and grounded elements is presented. The proposed oscillator can provide 2 sinusoidal output voltages with 90° phase difference. The condition of oscillation (CO) and frequency of oscillation can be electronically/orthogonally controlled by adjusting the bias current of the VDTA. The use of only grounded elements is ideal for integration. The PSpice simulation results are depicted. The given results agree well with the theoretical anticipation.
