Abstract
A new CMOS DC voltage doubler with nonoverlapping switching control is prop osed, in order to eliminate the dynamic current loss during switching as we ll as the threshold voltage drop of the serial switches. The simulated re s uits at 1.5 V show that the maximum power efficiency is improved with about 30% whereas the efficiency in the low output current region is larger than 5 times compared to the conventional voltage doublers. This proposed CMOS DC voltage doubler can be used as a VPP generator of low voltage DRAM's.
