High energy time domain temperature sensor for on chip thermal management

Abstract

The calibrated heat sensor is used for on chip heat sensing. We suggest an all digital on chip time based heat sensor for system on a chip (SoC) heat management. For on-chip purpose, the proposed temperature sensor achieves area-efficient and fast thermal monitoring by adopting a Digital Controlled Oscillator. The future heat sensor extinguishes the want for double position measurement compare to earlier heat sensors. The future sensor uses suggestion clock to execute auto measurement, also the operation delay is able to discard. Temperature measurement results are provided with a time based code generated by a simple counter. Afterwards, the exactness of the proposed temperature sensor is able to enhance by little area also small power utilization. This future heat sensor is able to simply measurement by a suggestion pulse.
