Abstract
A possible design of the compact sinusoidal quadrature oscillator using single voltage differencing transconductance amplifier (VDTA) and only two grounded capacitors has been presented. The presented quadrature oscillator provides the following attractive properties: (i) canonic form and resistor less structure; (ii) availability of the explicit quadrature voltage outputs and current outputs; (iii) electronic controllability of the oscillation frequency (Ω0); and (iv) low active and passive sensitivities. To support the validity of the oscillator, PSPICE simulation results have also been provided.
