An 8-bit, 10 kHz, 5.1 mu W, 0.18 mu m CMOS SAR ADC for RFID applications with sensing capabilities
An 5.1 μW, 1.8 V, 8-bit, successive approximation (SAR) analog-to-digital converter (ADC) using 10 kHz clock was designed and fabricated in a 0.18 μm CMOS technology for passive UHF radio frequency identification (RFID) applications. The ADC utilises a resistive digital to analog converter (DAC). The ADC can operate with low power consumption. The proposed comparator with cascode active load can offer large gain and can operate at a low supply voltage. The measured total power consumption is 5.1 μW at a 10 kHz input clock with a 1.8 V single supply, and 0.5 μW with 970 mV supply.
