Thermal sensors (TS) are essential for achieving optimized performance and\nreliability in the era of nanoscale microprocessor and system on chip (SoC). Compiling\nwith the low-power and small die area of the mobile computing, the presented TS supports\na wide range of sampling frequencies with an optimized power envelope. The TS supports\nup to 45 K samples/s, low average power consumption, as low as 20 W, and small core Si\narea of 0.013 mm2. Advanced circuit techniques are used in order to overcome process\nvariability, ensuring inaccuracy lower than �±2 �°C without any calibration. All this makes\nthe presented thermal sensor a cost-effective, low-power solution for 22 nm nanoscale\ndigital process technology.
