PIEZOELECTRIC RESONATOR TEMPERATURE DETERMINATION

Abstract:

A mobile device includes: a printed circuit board including circuit components and a plurality of traces that are electrically and thermally conductive; a piezoelectric resonator coupled to a subset of the traces by a plurality of connectors that are electrically and thermally conductive; a temperature sensor configured to provide an indication of temperature; and a thermal coupler coupled to the temperature sensor and to the plurality of connectors, the thermal coupler being thermally conductive and electrically insulative.
