Abstract
Various configurations and arrangements of systems and methods for compensating for variations in VCO output frequencies are described. A system in accordance with the disclosure can include an oscillator circuit including an oscillator, a first variable capacitance diode coupled to the oscillator and a second variable capacitance diode coupled to the oscillator. The system further includes a voltage source configured to apply a first voltage to the oscillator circuit to cause the output signal to comprise a selected frequency, the selected frequency being based on a received reference voltage. The system further includes a controller circuit configured to compare an operating voltage of the oscillator to the reference voltage while the first voltage is applied to the oscillator; and apply a second voltage to the oscillator circuit based on the comparison. The second voltage compensates for a difference between the reference voltage and the first voltage.
