The design and first measuring results of an ultra-low power 12bit Successive-Approximation ADC for autonomous multi-sensor systems are presented. The comparator and the DAC are optmised for the lowest power consumption. The proposed design has a power consumption of 0.52μW at a bitclock of 50-kHz and of 0.85μW at 100-kHz with a 1.2-V supply. As far as we know, the Figure-of-Merit of 66 fJ/convertion-step is the best reported so far. The ADC was realised in the NXP CMOS 0.14μm technology with… CONTINUE READING
