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~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...
Energy harvesters power energy-autonomous wireless sensor systems by converting ambient environmental energy into electrical energy. Thermoelectric generators (TEG's) are a suitable compact power supply for both on-the-body and industrial sensors. Due to changing conditions, the generated power and voltage vary. Therefore a power management circuit (PMC) has to store the generated energy in a rechargeable...
