Abstract :
This paper presents a 300 mV start-up technology for step-up DC-DC converters in energy harvesting systems. A cross-coupled multi-level charge pump improves start-up driving capability. And a voltage detector with reduced area and power cost is designed for the start-up voltage detection using less than 1 nA current. The proposed start-up system is designed under standard 0.18 um CMOS process.
