Abstract
A thermal sensor is propos ed for microprocessors,
which compares the BJT voltage to a reference by converting both
voltages t of r e q u e n c ya n dd i v i d i n gt h ef r e q u e n c i e st or e s u l ti na
digital number. The sensor has an rms resolution of ±0.2C and
an area of 0.02 mm² at the 32-nm process node and 0.006 mm² at
22 nm, i ncluding all digital processing circuitry. The conversion
rate is between 2–20 kS/s, which enables it to capture fast tran-
sients on the CPU. It consumes 3
