Abstract
Provided is a temperature-compensated voltage generating circuit that generates a temperature-compensated voltage which is supplied to an oscillator circuit. The temperature-compensated voltage generating circuit includes a temperature detecting circuit that detects a temperature; a high frequency attenuating part that attenuates at least a part of a frequency component which is higher than a direct-current component of an output of the temperature detecting circuit; an adder that adds the output of the temperature detecting circuit and an output of the high frequency attenuating part; and a compensated voltage generating part that generates the temperature-compensated voltage based on an output of the adder.
