Fully electronically tunable sinusoidal oscillator employing single VDTA and all grounded components

This article contributes a new configuration of the current mode (CM) sinusoidal oscillator employing a single voltage differencing transconductance amplifier (VDTA), as an active building block, and all grounded passive elements. This fully electronically tunable circuit offers independent control of its design parameters i.e., oscillation condition (OC) and oscillation frequency (OF). To validate the design concept, along with the regular mathematics, simulations have been performed using PSPICE software. Experimental results have been obtained by the commercially available IC i.e., LM13700, to validate the theoretical expectations.
