Abstract:
A method and apparatus for determining a temperature of a semiconductor device is provided herein. One aspect of the disclosed subject matter is seen in a temperature sensing device. The temperature sensing device comprises a diode and a circuit. The diode is adapted to be reverse biased by a charging voltage applied thereto. The circuit determines a temperature of the diode based on a rate that the voltage on the diode discharges in response to the charging voltage being uncoupled from the diode.
