With the focus of employing single Voltage Differencing Transconductance Amplifier (VDTA) in designing of electronically tunable oscillators, three configurations have been proposed in this manuscript. Each configuration enjoys an efficient integrated circuit implementation due to use of grounded capacitors. Unambiguous and independent control of its condition and frequency of oscillation is an additional feature which is available in all the configurations along with the quadrature outputs in voltage mode. The designed configurations have been tested both through simulation and experimental setup employing a newly proposed hardware arrangement of VDTA designed using off the shelf IC, i.e., OPA860. Moreover, the oscillators have also been experimentally justified with already available hardware realization of VDTA. Experimentation results generated using two different ICs, with two different hardware setups, have been tabulated so as to provide an illustrative study of the performances of oscillators.

在设计电子可调振荡器的过程中，以采用单压差跨导放大器（VDTA）为重点，在本手稿中提出了三种配置。由于使用了接地电容器，因此每种配置均可享受有效的集成电路实现。对其条件和振荡频率进行明确且独立的控制是一项附加功能，该功能可在所有配置中以及电压模式下的正交输出中使用。设计的配置已通过仿真和实验设置进行了测试，采用了新提议的VDTA硬件布置，该硬件布置是使用现成的IC（即OPA860）设计的。此外，振荡器还已经通过VDTA的可用硬件实现进行了实验验证。
