In this paper, the authors represent five sinusoidal oscillators based on the Operational TransResistance Amplifier (OTRA). The proposed circuits require single OTRA and a few passive components to generate oscillations. The condition of oscillation and frequency of oscillation of the first proposed circuit is controlled by a single grounded resistor. And the remaining circuits depend on independent control of condition of oscillation and frequency of oscillation. In all these proposed circuits the grounded resistor can be replaced by a grounded capacitor, which is important so far on integration point of view.
