This paper presents new sinusoidal oscillator employing operational amplifiers and six passive components with the advantage of easy tuning of oscillator frequency. Separate resistive elements control the frequency and the condition of oscillation. The easy control over the frequency and condition of oscillation through separate resistors makes the circuit practically feasible. The new proposed circuit provides three outputs with progressive quadrature relationship. Simulation results are presented using TINA software. The circuit is further experimentally tested for workablity by using different set of components. The new proposed circuit is verified using low cost general purpose operational amplifier.
