LEVEL SHIFTER IMPROVING DUTY RATE AND LEVEL SHIFTING METHOD USING THE SAME

摘要

When the duty ratio has a level shifting emphasis method using this and a level shifter that reduces the duty error is disclosed in.; A level shifter comprises a first inverter, an input generator, a comparator and a second inverted group. Receiving input generator comprises an input signal and an inverted input signal and generates an input signal of the complementary first level having the same signal characteristics. The level-shifting method includes a first reversing step, the stimulus generation step, comparing step and the second reversing step. Therefore, it is possible to minimize the duty error of the level shifter.
