Abstract
A new sinusoidal oscillator circuit using only operational amplifiers (OA's) and resistors, which is attractive for monolithic IC fabrication, is presented. The circuit can be made to oscillate by adjusting a resistor ratio, while its frequency can be controlled over a wide range by a grounded resistor, independent of condition of oscillation. Experimental results are given which agree with the theoretical analysis.Keywords
