Abstract (in Japanese) (See Japanese page) 
(in English) A fully integrated step-up DC-DC converter for energy harvesting applications is presented. A minimum startup voltage of 100 mV is achieved by the startup mechanism based on an LC oscillator (LCO). Conventional voltage converters with the LCO-based startup mechanism provide a significantly low conversion efficiency of around 1%. To overcome this drawback, the following two circuit techniques are proposed in this technical report: 1) a gate-boosted charge pump and 2) an LCO deactivation. The proposed voltage converter is fabricated in the 65nm silicon on thin buried oxide (SOTB) process. The measurement results show that when the input voltage is 100 mV, the proposed converter can provide an output of 760 mV at a conversion efficiency of 33%, which is the highest efficiency compared with the conventional fully integrated voltage converters.
