  • PN-junction temperature sensing apparatus
    Patent number: 7758240
    Abstract: A PN-junction temperature sensing apparatus for applying input signals to a semiconductor device and measuring temperature-dependent output signals has an odd number of current sources (1, 2, n) switches (5, 6, 7) with selectable outputs to connect the current sources (5, 6, 7) with a thermal sensor (12) or a sink diode (13) and an A/D converter (17) to digitize the measured voltage of the thermal sensor (12). A digital processor (18) controls the switches (5, 6, 7) and stores the digitized voltage values in a memory. Provided algorithms allow the usage of these values to provide a calibrated measurement of temperature and also sensor life estimation.
