LEVEL SHIFTING CIRCUIT

摘要

A level shifting circuit includes a level shifting portion configured to receive an input signal and generate an output signal, and a current adjustment circuit connected between the level shifting portion and a drive high voltage node at which a drive high voltage is applied. The current adjustment circuit is configured to adjust an amount of current provided from the drive high voltage node to the level shifting portion.

1. A level shifting circuit, comprising:
a level shifting portion configured to receive an input signal and generate an output signal; and a current adjustment circuit connected between the level shifting portion and a drive high voltage node at which a drive high voltage is applied, and configured to adjust an amount of a current provided from the drive high voltage node to the level shifting portion, wherein the current adjustment circuit comprises: a first current adjustment transistor connected between the drive high voltage node and the level shifting portion, and configured to adjust a first current to be provided to a first node of the level shifting portion; and a second current adjustment transistor connected between the drive high voltage node and the level shifting portion, and configured to adjust a second current to be provided to a second node of the level shifting portion, wherein the first and second current adjustment transistors are turned on regardless of the input signal.
