Abstract EN
A new configuration of voltage-mode quadrature sinusoidal oscillator is proposed.
The proposed oscillator employs two voltage differencing current conveyors (VDCCs), two resistors, and two grounded capacitors.
In this design, the use of multiple/dual output terminal active building block is not required.
The tuning of frequency of oscillation (FO) can be done electronically by adjusting the bias current of active device without affecting condition of oscillation (CO).
The electronic tuning can be done by controlling the bias current using a digital circuit.
The amplitude of two sinusoidal outputs is equal when the frequency of oscillation is tuned.
This makes the sinusoidal output voltages meet good total harmonic distortions (THD).
Moreover, the proposed circuit can provide the sinusoidal output current with high impedance which is connected to external load or to another circuit without the use of buffer device.
To confirm that the oscillator can generate the quadrature sinusoidal output signal, the experimental results using VDCC constructed from commercially available ICs are also included.
The experimental results agree well with theoretical anticipation.
