Abstract

Level shifter and related apparatus are provided. The level shifter has first to sixth transistors, wherein drains of the first and the second transistors respectively are coupled to drains of the fifth and the sixth transistors as two output nodes of the level shifter, gates of the fifth and the sixth transistors are two input nodes of the level shifter. A source, a drain and a gate of the third transistor are respectively coupled to a gate of the first transistor, the drain of the sixth transistor and a first bias voltage, and a source, a drain and a gate of the fourth transistor are respectively coupled to a gate of the second transistor, the drain of the fifth transistor and a second bias voltage.
