Abstract

Microprocessors and SoCs employ multiple temperature sensors to prevent overheating and ensure reliable operation. Such sensors should be small (<10,000μm2) to monitor local hot-spots in dense layouts. They should also be moderately accurate (1°C) up to high temperatures (≥125°C), so that the system throttling temperature can be set as close as possible to the maximum allowable die temperature. Furthermore, they should be fast (1kS/s) and consume low power (tens of μW).
