Abstract
The increasing development of IoT technologies has allowed the design of sensors enabling the simultaneous wireless information and power transfer (SWIPT), making compactness and miniaturization important prerogatives of this new paradigm. This paper presents the design of a SWIPT circuit that exploits a single circuital implementation for both energy harvesting purposes and signal demodulation, overcoming the need for designing two different dedicated circuit boards. The simulation results show about 50% of RFto-dc power conversion efficiency with –10 dBm of input power and demonstrate the possibility to demodulate the received signal to retrieve the data coming from the same frequencymodulated Bluetooth low energy signalI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
