ABSTRACT:
A level shifter and method thereof. The level shifter may include a protective circuit configured to receive an input signal having an input voltage level, the input signal received on an input line, the protective circuit reducing the input voltage level to generate a stabilized input signal and a first inverter configured to invert the stabilized input signal and to output an inverted output signal at an inverted output voltage level to a first node. In an example method, an input signal may be received at an input voltage level, the input voltage level may be reduced to output a stabilized input signal, the stabilized input signal may be inverted to output an inverted output signal at an inverted output voltage level to a first node and the first node may be transitioned to a node voltage level based on the input signal. The level shifter and method thereof may reduce a power consumption and/or a chip size of a semiconductor device.
