Abstract
A temperature sensor device is capable of measuring minute temperature changes while being manufactured at low cost without needing a high performance IC tester. A temperature sensor device includes a temperature sensor circuitand a temperature sensor. The temperature sensorincludes a PN junction elementwhich is a temperature sensing element, a variable current source which supplies different forward currents of at least two values to the PN junction elementand a constant voltage sourcewhich outputs a constant voltage having the same temperature properties as a forward voltage of the PN junction element
