Abstract
There are provided a level shifter circuit and a gate driver circuit including the same. The level shifter circuit includes: a plurality of switching devices connected to a predetermined DC power supply through a resistor and operated by different driving signals; a gain conversion unit operated by first signals output from the plurality of switching devices, respectively, and generating second signals having a level within a predetermined range of the first signals; and a noise removal unit connected to at least one output terminal among the plurality of switching devices to prevent malfunctioning of the gain conversion unit, wherein the gain conversion unit inputs the second signals to a high side gate driver circuit through an inverter circuit.
