A low power smart temperature sensor followed by an SC amplifier and a 12bit Successive-Approximation analogue-digital converter (ADC) to compensate temperature deviation in drug electrochemical detection, is here presented.

Abstract
A low power smart temperature sensor followed by an SC amplifier and a 12bit Successive-Approximation analogue-digital converter (ADC) to compensate temperature deviation in drug electrochemical detection, is here presented. The proposed design is accurate within 0.1°C over the temperature range of -55°C to 125°C. A PTAT voltage is used for temperature monitoring. The succeeding ADC digitizes the output with a bit-clock of 50-kHz. The ADC has a Figure-of-Merit of 66 fJ/conversion-step. The system is implemented in an NXP CMOS 0.14μm technology. The die area is 0.21 mm2 and the whole system consumes less than 16μW for 1.2V of voltage supply.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
