Abstract

There are many inventions described and illustrated herein. In one aspect, the present inventions relate to a temperature measurement system comprising (1) a first microelectromechanical resonator to generate a first output signal having a frequency that varies with operating temperature, wherein the first microelectromechanical resonator includes a frequency function of temperature; (2) a second microelectromechanical resonator to generate a second output signal having a frequency that varies with operating temperature, wherein the second microelectromechanical resonator includes a frequency function of temperature; and (3) frequency division circuitry, coupled to the first and second microelectromechanical resonators, to determine data which is representative of the operating temperature of the first and/or second microelectromechanical resonator using (i) data which is representative of the frequency of the first output signal and (ii) data which is representative of the frequency of the second output signal. The frequency division circuitry may include circuitry to divide the frequency of the first output signal by the frequency of the second output signal (whether in digital or analog domain).
