Sustainable and Low-Power Logic Inverter-Based Batteryless SLIPT Receiver for IoT Nodes

This study delves into a batteryless Simultaneous Light Information and Power Transfer (SLIPT) receiver design utilizing a logic inverter. Unlike conventional amplifier-based receivers, which are power-intensive and necessitate larger hardware with a significant CO

footprint due to their bandwidth requirements, our proposed method employs a logic inverter as the receiver’s amplifier in a back-to-back configuration. This approach advocates for reduced environmental impact in IoT nodes that integrate a photovoltaic (PV) panel for energy harvesting and serve as a data communication frontend. Our approach demonstrates the potential for communication bandwidth ranging from 200 kHz to 1.5 MHz. Simultaneously, power harvesting levels vary between 9.25 μW and 306 μW, depending on the type of PV panel utilized.
