Abstract
A temperature sensor having a process compensated current generator (37) for use in a temperature sensing circuit (35) and a current comparator (40). The current generated in reference current generator (36) provides a complementary distortion to balance the effect introduced by processing into the two circuits which make up temperature dependent current generator (38). The generator generates two currents which are used to measure temperature changes. The generator including both PFET and bipolar devices, where the generator compensates for variations in processing conditions. According to one embodiment, the temperature sensor includes a process compensation generator which provides an indicator as a function of at least one processing parameter and a current generator which adjusts the currents according to the indicator.
