Abstract
Official abstract text for this publication.
Electronic apparatus that can suppress the operating voltage of an incorporated semiconductor integrated circuit to a low voltage is provided. Electronic apparatus 1 includes a power supply circuit 13 , a semiconductor integrated circuit 10 that operates by a supply voltage supplied from the power supply circuit 13 , and a temperature sensor 11 that measures the temperature of the semiconductor integrated circuit 10 . The power supply circuit 13 decreases the supply voltage according to a rise in the measured temperature.
