Abstract
This invention provides a temperature sensor circuit and its operation method. The temperature sensor circuit includes a temperature sensor, a temperature comparator, a plurality of temperature sensor enable clocks with different clock cycles and a clock selection circuit. The temperature sensor detects a temperature of an Integrated circuit and sending a signal indicative of the temperature. The temperature comparator executes a comparison between the temperature of the Integrated circuit and a predetermined temperature setting upon receiving the signal indicative of the temperature and sending an output according to the comparison. Upon receiving the output, the clock selection circuit provides one of the temperature sensor enable clocks according to the output to enable the temperature sensor. The temperature detection cycle of the temperature sensor is thus adjustable to save the temperature sensor power.
