  • Level shifter with improved operation
    Patent number: 9136845
    Abstract: A level shifter includes a first branch and a second branch. A trigger of the first branch is coupled to a low voltage input, an inverted high voltage output and a ground. A latch of the first branch is coupled to the inverted high voltage output and a high voltage output. A power gate of the first branch is coupled to an inverted low voltage input, the latch of the first branch and a high voltage supply. A trigger of the second branch is coupled to the inverted low voltage input, the high voltage output and the ground. A latch of the second branch is coupled to the high voltage output and the inverted high voltage output. A power gate of the second branch is coupled to the low voltage input, the latch of the second branch and the high voltage supply.
