Claim:
1. A method for determining a temperature measurement, the method comprising: providing an integrated circuit device; measuring a first temperature using a temperature sensor; determining a first reference value for the integrated circuit device at the first temperature, the reference value being based on at least a temperature, a first delay electrical characteristic, and a design constant associated with the integrated circuit, the first reference value being proportional to the first temperature; measuring a second delay electrical characteristic for the integrated circuit device; determining a second reference value for the integrated circuit based on the second delay electrical characteristic and an equivalent temperature; determining a gain value associated with the temperature sensor using at least the first reference value and the second reference value; generating a line equation using at least the gain value; measuring a third delay electrical characteristic comprising a differential signal from a first delay core and a second delay core receiving a common feedback voltage; and determining a third temperature using the third delay electrical characteristic and the line equation.
