Abstract
A temperature sensor integrated in a transistor array, e.g., metal-oxide-semiconductor field-effect transistor (MOSFET) array, is provided. The integrated temperature sensor may include a doped well region formed in a substrate (e.g., SiC substrate), a resistor gate formed over the doped well region, first and second sensor terminals conductively coupled to the doped well region on opposite sides of the resistor gate. The integrated temperature sensor includes a gate driver to apply a voltage to the resistor gate that affects a resistance of the doped well region below the resistor gate, and temperature analysis circuitry to determine a resistance of a conductive path passing through the doped well region, and determine a temperature associated with the transistor array.
