Abstract
A system and a method for measuring temperature within an operating circuit use a Wheatstone bridge within a temperature sensing circuit. One of the resistors in the Wheatstone bridge is a thermally sensitive resistive material layer within the operating circuit. The other three resistors are thermally isolated from the operating circuit. Particular configurations of NFET and PFET devices are used to provide enhanced measurement sensitivity within the temperature sensing circuit that includes the Wheatstone bridge.
