Abstract :
This paper reports design, efficiency and measurement results of the temperature sensor based on substrate bipolar transistors and a PTAT multiplier for adaptive thermal monitoring of deep-submicron VLSI circuits. The prototype temperature sensor with un-calibrated 3σ accuracy of 0.9°C within a 0°C-160°C temperature range has been fabricated in standard single poly, six metal 90nm CMOS, consumes only 11μW at 1V power supply and measures 0.05mm2.
