We present a field-programmable analog array (FPAA) for sensor interfacing and information extraction in resource-constrained applications. Ultra-low-power operation is achieved through low-overhead reprogramming and an efficient processing architecture. We demonstrate reconfigurability and performance through the synthesis of a temperature sensor, heart-rate alarm, and audio spectrum normalizer, which have measured full-system power consumption of 12μW, 20μW, and 17.25μW, respectively.
