Abstract(s) :

(Anglais) As the Internet of Things (IoT) evolves to become a ubiquitous technology, the development of its enabling technologies presents several challenges to circuit designers. Among them, the proper design of the short‐range communication systems of the IoT sensor node, which must normally remain operable for weeks, months, or even years supplied by a single battery or by means of energy‐harvesting (EH) techniques. Within the latter, wireless power transmission (WPT) emerges as a suitable technique for powering battery‐free sensors from radio‐frequency (RF) energy available in the environment, as proven through numerous applications reported in the state‐of‐the‐art literature. However, the amount of high‐frequency energy that can be collected is limited, whereas the attainable voltage supply normally remains below 1 V. Therefore, designers must exploit ultra‐low power (ULP) and ultra‐low voltage (ULV) design strategies in order to make the RF front‐end operable under such constraints. This chapter presents the design of a ULP−ULV RF‐powered CMOS front‐end that can be used to interface low‐rate autonomous sensors. The circuit was designed in a 65‐nm CMOS technology and operates with a 0.5 V supply that is harvested from a 2.4 GHz RF signal. The main building blocks include the harvester, the voltage multiplier, the wake‐up, and power management unit, the on‐off keying (OOK)‐modulated voltage‐controlled oscillator (VCO), the class‐E power amplifier, and digital circuitry for reading an external sensor output and controlling the front‐end operation.
