【 摘 要 】

This paper deals with the issue of the initial start-up of an autonomous and battery-free system powered by an energy harvester associated with a storage subsystem based on supercapacitors initially discharged. A review of different low power Under Voltage Lock-Out (UVLO) solutions used to delay the load start-up and to avoid a useless discharge of supercapacitors is presented and discussed.
