This paper describes circuit architectures and techniques to meet the specialized requirements of energy autonomous micro-sensor nodes. We address the fundamental components, namely the ADC, DSP, and radio, at the node-level to isolate important optimizations and functions. Using prototyped implementations, low energy and power-aware circuits are presented. These, state-of-the-art techniques demonstrate that practical self-powered nodes are possible.
