Linear vt-based temperature sensors with low process sensitivity and improved power supply headroom

— A new on-die temperature sensor that operates at low supply voltages and exhibits low process sensitivity and good linearity over a wide temperature range is introduced. When compared to conventional structures which have limited supply voltage headroom at the slow-n process corner, the new structures have sufficient headroom to practically operate well over all process corners. When implemented in a TSMC 0.18um
