  • Systems and method for level shifters
    Patent number: 8847659
    Abstract: A level shifter system includes an inverting portion, a non-inverting portion and a cross latch output component. The inverting portion is configured to receive an inverting input, a supply voltage and to generate an intermediary inverting output. The non-inverting portion is configured to receive a non-inverting input, the supply voltage and to generate an intermediary non-inverting output. The cross latch output component is configured to drive the intermediary inverting and non-inverting outputs to inverting and non-inverting outputs, respectively. The inverting and non-inverting outputs are at selected upper and lower levels according to the inverting input and non-inverting inputs, respectively.
