ABSTRACT:
A compensation circuit including resistors, capacitors and a varactor diode powered simultaneously by the same voltage source applied to a voltage controlled oscillator for reducing deviation from a desired oscillator output frequency on power-up. When power is applied, an exponentially varying voltage is applied to the varactor diode changing its capacitance in such a manner as to change the oscillator frequency in the opposite direction to its natural drift tendency, thus producing a substantially constant output frequency over the period of interest.
