MULTI-POINT TEMPERATURE SENSING METHOD FOR INTEGRATED CIRCUIT CHIP AND SYSTEM OF THE SAME

摘要

A multi-point temperature sensing method for integrated circuit chips and a system of the same are revealed. The system includes at least one slave temperature sensor embedded at preset positions for measuring temperature of a block and a master temperature sensor embedded in an integrated circuit chip and electrically connected to each slave temperature sensor. Variations of the slave temperature sensor induced by variations of process, voltage and temperature are corrected by the master temperature sensor. Thus the area the temperature sensors required on the integrated circuit chip is dramatically reduced and the stability of the temperature control system is improved. The problem of conventional System-on-a-Chip that only a limited number of temperature sensors could be used due to the area they occupied can be solved.

1. A multi-point temperature sensing system for an integrated circuit chip having a plurality of blocks executing specific functions comprising:
at least one slave temperature sensor mounted in the block so that each preset position for measuring temperature of the block is arranged with the slave temperature sensor; and a master temperature sensor embedded in the integrated circuit chip and electrically connected to the slave temperature sensor; wherein the master temperature sensor corrects variations of the slave temperature sensor induced by variations of process, voltage and temperature.
