Abstract
An apparatus comprises a first circuit and a second circuit. The first circuit may be configured to generate an output signal having a first frequency in response to a voltage level of a first input signal and a value of a second input signal. The second circuit may be configured to determine the value of the second input signal based on a reference frequency signal, the first frequency of the output signal, a reference voltage, and a value representing a target frequency for the output signal.
