Systems and method for level shifters

摘要

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.

1. A level shifter system comprising:
an inverting portion including first and second transistors and being configured to receive an inverting input on both a source of the first transistor and a gate of the second transistor and configured to receive a power supply and further configured to generate an intermediary inverting output based on the inverting input and the power supply; a non-inverting portion configured to receive a non-inverting input and the power supply and to generate an intermediary non-inverting output; and a cross latch output component configured to drive the intermediary inverting and non-inverting outputs to inverting and non-inverting outputs, respectively, the inverting and non-inverting outputs being at selected upper and lower levels according to the inverting input and non-inverting input, respectively.
