Abstract
A circuit includes an oscillator having a driver and a resonator. The driver receives a supply voltage at a supply input and provides a drive output to drive the resonator to generate an oscillator output signal. A power converter receives an input voltage and generates the supply voltage to the supply input of the driver. The power converter varies the supply voltage based on an adjust command supplied to a command input of the power converter. A detector monitors a voltage level of the oscillator output signal. A controller sets the adjust command to the power converter to control the supply voltage to the supply input of the driver such that the voltage level of the oscillator output signal is set at or above a predetermined threshold voltage.
