Abstract

An 25-muW 1.8V 8-bit 10 kS/s successive approximation (SAR) analog to digital converter (ADC) was designed and fabricated in a 0.18 mum CMOS technology for passive UHF RFID applications. The resistive digital to analog converter (DAC) has no sample and hold block and can operate with low power consumption. The proposed comparator can operate at a low supply voltage. The measured total power consumption is 25 muW at a 10 kS/s conversion rate with a 1.8V single supply voltage.
