A method and circuit are disclosed for measuring temperature. An exemplary embodiment of the present invention includes a first oscillator circuit that generates a first signal having a frequency that is dependent upon a sensed temperature. Difference circuitry determines a difference in frequency between the first signal and the second signal having a frequency that is substantially independent of temperature, and generates a difference signal having a number of pulses thereon based upon the difference. A counter circuit is responsive to the difference circuitry for offsetting a predetermined temperature level based upon the pulses appearing on the difference signal, to obtain an output signal indicative of the sensed temperature.
