Abstract
An adjustable voltage controlled oscillator has an input for receiving a voltage signal and an integrator coupled to the input for generating a ramp signal. The circuit also includes an adjustable current supply coupled to an output of the integrator for supplying an adjustable amount of current. A comparator compares the ramp signal with a predetermined voltage. The circuit further includes an output for generating a frequency output as a function of the comparison, wherein the circuit is calibratible by adjusting current generated by the adjustable current supply.
