Abstract: From a circuit implementation perspective, this paper presents a brief overview of simultaneous wireless information and power transmission (SWIPT). By using zero-power batteryless wireless sensors, SWIPT mixes wireless power transmission with wireless communications to allow the truly practical implementation of the Internet of Things as well as many other applications. In this paper technical backgrounds, problem formation, state-of-the-art solutions, circuit implementation examples and system integrations of SWIPT are presented.

Keywords: simultaneous wireless information and power transmission (SWIPT) systems; backscatter communication; low power communication
