SYSTEM AND METHODS FOR THERMAL CONTROL USING SENSORS ON DIE

摘要

A portable electronic device including a temperature sensor embedded in a die is provided. To process temperature measurements the portable electronic device includes a processor circuit coupled to the temperature sensor, the processor circuit configured to read a measurement from the temperature sensor when an integrated circuit in the die is inactive. Furthermore, a memory circuit coupled to the processor circuit and the temperature sensor stores a temperature gradient provided by the temperature sensor. A Printed Circuit Board for use in a portable electronic device as above is also provided. A method for performing thermal control in a portable electronic device as above is also provided.
