This paper describes the design of a temperature sensor in 65-nm CMOS technology, intended for food monitoring in IOT and RFID contexts. The digitally-assisted readout scheme combined with a reduced design complexity in the PNP BJT sensor analog front-end allows the minimization of the power consumption. The full sensor occupies an area of 0.26 mm2, with an inaccuracy of ±0.37°C over the [-20°C ÷ 80°C] temperature range, and a power consumption lower than 15.5 µW with a conversion speed of 30 ms.

Abstract
This paper describes the design of a temperature sensor in 65-nm CMOS technology, intended for food monitoring in IOT and RFID contexts. The digitally-assisted readout scheme combined with a reduced design complexity in the PNP BJT sensor analog front-end allows the minimization of the power consumption. The full sensor occupies an area of 0.26 mm2, with an inaccuracy of ±0.37°C over the [-20°C ÷ 80°C] temperature range, and a power consumption lower than 15.5 µW with a conversion speed of 30 ms.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
