  • Abstract
    A low-energy 8-bit charge-redistribution SAR ADC for wireless sensor nodes is proposed. The ADC employs a new capacitor switching procedure that allows a reduction of the average switching energy as compared to previous proposals. Simulation and measurement results of a test chip prototype operating at 100 kS/s are provided, showing a SFDR of 55.63 dB for a power consumption of 2.17 μW. The active area of the ADC is only 0.275 mm2.
