Abstract
The present disclosure describes circuits (e.g., clock synthesizers) and methods for producing alternating signals. A clock synthesizer includes an oscillator, a voltage control circuit, and a frequency control circuit. The oscillator produces an output signal with a frequency. The voltage control circuit produces a control voltage for the oscillator based on the frequency of the output signal. The frequency control circuit produces a control signal for the oscillator based on (i) an input voltage to the frequency control circuit and (ii) the control voltage. The control signal causes the oscillator to adjust the frequency of the output signal such that the voltage control circuit adjusts the control voltage to be closer to the input voltage.
