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 CO2 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 mu W and 306 mu W, depending on the type of PV panel utilized.
