Abstract
A noise detection circuit includes a first delay circuit which has a propagation delay of a first delay time when a signal propagates therethrough and a second delay circuit which has a propagation delay of a second delay time when the signal propagates therethrough, and outputs, based on a sum of the first delay time and the second delay time, a detection result indicating the magnitude of noise on power supply voltage applied to the first delay circuit and the second delay circuit. A control unit controls, based on the detection result, a frequency of a clock signal supplied to a circuit unit to which the power supply voltage is applied and the second delay time in such a manner as to exhibit an opposite behavior to a change in the first delay time induced by temperature.
