ABSTRACT
A new sinusoidal oscillator circuit is presented using two
capacitors, two resistors and a single current conveyor. The
analytical expressions are obtained, both by assuming the current
conveyor to be ideal and by taking the tracking errors into
account. It has been shown that the slightly greater than unity
value of loop gain required to maintain sustained oscillations is
provided by taking the tracking errors into account. Simulation
and experimental results are presented. The circuit presented
generates perfectly sinusoidal waves in the audible frequency
range and enjoys low sensitivity.
