A 1.6mW 300mV-supply 2.4GHz receiver with −94dBm sensitivity for energy-harvesting applications

The goal of this work was to design a 2.4GHz receiver that operates with a supply voltage of 300mV, allowing direct powering from various energy-harvesting sources. Our target application is body-worn wireless devices requiring high datarates (wirelessly tethered hearing aids, for example). This application allows access to multiple energy-harvesting power sources, like photovoltaic and thermoelectric power harvested from body heat.
