This paper describes the architecture of a smart temperature sensor designed in CMOS 65nm technology node, intended for IOT and RFID applications. The shift of the trimming circuitry and of a portion of the readout operations into the digital domain, combined with a reduced design complexity in the sensor analog front-end, allow the min- imization of the power consumption. The maximum inaccuracy of the sensor, obtained by means of a two point calibration, is ±0.3o C over the [-40°C÷125°C] temperature range, with an average power consumption of 375 nW at a conversion speed of 1 Sa/s.

Abstract
This paper describes the architecture of a smart temperature sensor designed in CMOS 65nm technology node, intended for IOT and RFID applications. The shift of the trimming circuitry and of a portion of the readout operations into the digital domain, combined with a reduced design complexity in the sensor analog front-end, allow the min- imization of the power consumption. The maximum inaccuracy of the sensor, obtained by means of a two point calibration, is ±0.3o C over the [-40°C÷125°C] temperature range, with an average power consumption of 375 nW at a conversion speed of 1 Sa/s.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
