A digital-based, process-supply-and-temperature independent voltage reference suitable to nanoscale CMOS technologies, which exploits the recently proposed ‘virtual reference’ concept to achieve a very low thermal drift, is presented. Its performance is assessed on the basis of simulations and experiments carried out on a microcontroller-based, proof-of-concept prototype and is compared with state-of-the-art integrated analogue and digital voltage references. A simulated (measured) thermal drift as low as 1 ppm/°C (5 ppm/°C) in the temperature range −40/+140°C (−10/+100°C) is reported.

Abstract
A digital-based, process-supply-and-temperature independent voltage reference suitable to nanoscale CMOS technologies, which exploits the recently proposed ‘virtual reference’ concept to achieve a very low thermal drift, is presented. Its performance is assessed on the basis of simulations and experiments carried out on a microcontroller-based, proof-of-concept prototype and is compared with state-of-the-art integrated analogue and digital voltage references. A simulated (measured) thermal drift as low as 1 ppm/°C (5 ppm/°C) in the temperature range −40/+140°C (−10/+100°C) is reported.File | Dimensione | Formato | |
