Abstract
This paper presents a fully-integrated µW-level
photovoltaic (PV) self-sustainin g energy harvesting system pro-
posed for smart nodes of Intern et of Things (IOT) networks. A
hysteresis regulation is designed to provide a constant 3.3 V output
voltage for a host of applications, including powering sensors,
signal processors, and wireless tr ansmitters. Due to the stringent
power budget in IOT scenarios, the power consumption of the
harvesting system is optimized by multiple system and circuit
