Abstract
A voltage level shifter including a voltage converting unit to convert an input voltage into a current; a voltage level shifting unit to drive a driving voltage based on the current and shift a voltage level of the driving voltage when a modulation voltage is applied at a first voltage level to a floating ground; a circuit driving voltage supply unit to supply a circuit driving voltage and further to generate a shifted voltage level of the circuit driving voltage when the modulation voltage is applied at the first voltage level; and an output unit to supply an output voltage based on the circuit driving voltage and the driving voltage, and further supply the output voltage at a second voltage level based on the shifted voltage level of the driving voltage and the circuit driving voltage when the modulation voltage is applied at the first voltage level is disclosed.
