Abstract
A system and method for level shifting a core, lower voltage in a one-stage level shift device to produce a higher, driving voltage. The system includes a first device that optimally functions with a first voltage and that outputs the first voltage. The system also includes a one-stage level shift device that receives the first voltage and shifts the first voltage to a second voltage without an intermediate voltage, the second voltage being higher than the first voltage. The system also includes a second device that receives the second voltage to optimally function. In some cases, the first voltage can be a periodic wave such that the higher voltage is produced with one portion of the level shift device during a first portion of the wave and another portion of the level shift device during a second portion of the wave.
