ABSTRACT:
In some embodiments, a circuit includes an oscillator circuit and a control circuit. The oscillator circuit generates a clock signal and includes a selectable delay circuit. The control circuit receives the clock signal from the oscillator and a reference signal. The control circuit provides a control signal to the oscillator circuit to activate the selectable delay circuit to change the frequency of the clock signal. In some embodiments, a method includes generating a clock signal in an oscillator circuit, processing the clock signal to generate a control signal, and activating a selectable delay circuit in the oscillator circuit, in response to the control signal.
