Abstract
A level shifter includes a pre-level shifter and a selector. The selector is coupled to the pre-level shifter. The pre-level shifter shifts an input digital voltage to a first digital voltage and a second digital voltage. The levels of the first digital voltage and the second digital voltage transition sequentially in time when the level of the input digital voltage transitions from one logic to the other. The selector selects and outputs the first digital voltage whose level transitions earlier in time compared to the transition of the level of the second digital voltage.
