Abstract: An oscillator control circuit includes a zero-temperature coefficient (ZTC) estimator estimating a ZTC voltage based on a supply voltage supplied to the oscillator and a frequency of an oscillation signal output by the oscillator. The ZTC voltage is the magnitude of the supply voltage VDD which corresponds to the ZTC condition for the oscillator. The ZTC estimator generates a bias control signal such that the magnitude of the supply voltage becomes the ZTC voltage.
