Level conversion device and method

A device, comprising:

• a level shifter, comprising a first transistor and a second transistor, wherein a gate terminal of the first transistor is configured to receive a first input signal, and a gate terminal of the second transistor is configured to receive a second input signal having a logic value different from that of the first input signal;
• a third transistor having a first terminal coupled to a first output terminal of the level shifter to receive a first output signal and a gate terminal to receive the second input signal;
• and
• a fourth transistor having a first terminal coupled to a second output terminal, different from the first output terminal, of the level shifter to receive a second output signal and a gate terminal configured to receive the second input signal;
• wherein the first output signal and the second output signal have logic values different from each other.

A method, comprising:

• in response to a first input signal having a first logic level, generating, by a level shifter, a first output signal at a first output terminal of the level shifter;
• in response to the first input signal having a second logic level, generating, by the level shifter, a second output signal at a second output terminal of the level shifter;
• receiving, by a selector, the first output signal at a first input terminal of the selector and the second output signal at a second input terminal of the selector;
• and
• selecting, by the selector, the first output signal or the second output signal as a selected signal to be output to an output stage in response to the first input signal received at both of a third input terminal of the selector and a fourth input terminal of the selector,
• wherein the first to fourth terminals of the selector are different from each other.
