This Letter presents a new real-time and compact current-mode temperature sensor for system-on-chip thermal monitoring. The proposed temperature sensor provides a low-cost readout scheme that utilises a current switching comparator and dual-control bucket searching algorithm. It does not require an ADC or charged capacitor with large area and power dissipation. The dynamic element matching and threshold-setting techniques are employed to further increase the accuracy of the proposed sensor. It is fabricated with a standard 55 nm CMOS process, achieves an accuracy of while occupying a silicon area of , and consumes with a conversion time.
