摘要：
A high efficiency power management system for solar energy harvesting applications is proposed. The power management system receives power from photovoltaic (PV) cell and generate different voltage levels, they are 1V similar to 0.3V for analog circuitry and low power digital circuitry, -1.2V for super-cutoff technique in memory circuitry, and 10V for FLASH memory or I/O components. The great voltage varieties are suitable for green integrated regulator SoC electronics. The power management system also contains a rechargeable battery which is charged by multi-phase maximum power tracking (MPT) circuitry with the PV cell module. With the MPT circuitry, the power of PV cell can be regulated in the maximum power region. The average power efficiency of the MPT circuitry is up to 80%similar to 73%. All resultsare simulated in UMC 90nm bulk CMOS technology model.
