Abstract
An apparatus includes a first oscillator to generate an output signal that has a first frequency. The apparatus further includes a second oscillator to generate an output signal that has a second frequency. The second frequency varies as a function of temperature. The apparatus further includes a controller that counts a number of cycles of the output signal of the second oscillator in order to determine whether to calibrate the first oscillator.
