ULTRA-LOW POWER VOLTAGE REFERENCE & TEMPERATURE SENSOR

The emergence of internet-of-things technology has led to an increasing demand for efficient stable power supplies, with low sensitivity to temperature and supply quality.

University of Utah researchers have created an ultra-low power, highly stable voltage reference for 65nm CMOS circuits with lower PVT sensitivity. The temperature sensor is built on the low-power voltage reference design and provides a digital friendly and accurate output from -20 to +80°C with a max error of +/-.23°C while consuming only 11nW.
