extend system lifetime for internet of everything (IoE) nodes. Ambient light is a common energy source that can be harvested by photovoltaic (PV) cells. However, light intensity varies widely depending on location, ranging from ~10s of lux in dim indoor conditions to ~100klux under direct sunlight. Designing a fully integrated light harvester that spans such a wide range of light intensity with high efficiency is challenging, especially since typically low PV cell voltage requires a high upconversion ratio and PV-cell voltage/current characteristics change significantly with light intensity. Boost DC-DC converters are a typical energy-harvesting solution with high conversion efficiency, but they require a large off-chip inductor and hence cannot be fully integrated, increasing system size [1-3].
