Claim:
1. A system for determining a temperature of a location in electronic circuitry, comprising: first circuitry, in proximity to the location in the electronic circuitry, configured to adjust first and second output voltages as a function of an operating temperature of the electronic circuitry at the location; second circuitry configured to convert the first and second output voltages to a first voltage signal that is proportional to the operating temperature; third circuitry configured to convert the second output voltage to a second voltage signal that is inversely proportional to the operating temperature; fourth circuitry configured to determine a difference between the first voltage signal and the second voltage signal to produce a difference voltage value, including: fifth circuitry configured to determine the temperature of the location in the electronic circuitry as a function of the difference voltage value.
