Abstract
A temperature sensor using a novel process-invariant temperature sensing element and voltage to current converter for battery-operated ultra-low power micro systems is proposed. By introducing a new temperature-to-voltage sensing element that outputs only 75mV, the sensor achieves ultra-low power. The sensor was implemented in 180nm CMOS process and uses 0.09mm2 of area. Measurements from test chips show 65nW power consumption, the lowest reported to date, with an inaccuracy of +1.3oC /-1.4oC across 0oC to 100oC after 2-point calibration.
