Ultra low energy FDSOI asynchronous reconfiguration network for an IoT wireless sensor network node

Abstract

The paper describes a new asynchronous communication network for reconfiguration of adaptive Wireless Sensor Network (WSN) nodes. The use of adaptive blocks is motivated by the need to increase the performance of the node while being energy efficient. They are able to adapt their performance to the environment, the energy budget and the task. The purpose of the proposed communication network is to handle control signals, both in sleep and working mode of the node at a low energy cost. We show that we can achieve a 0.07pJ/bit in energy per bit and 1.1ns/bit in latency in a 28nm FDSOI technology at 0.6V in asynchronous QDI logic.
