Abstract
The present invention provides a level shift circuit capable of operating at low input voltage. The level shift circuit comprises: a first switch element coupled to a first output terminal, a second switch element coupled to a second output terminal, a third switch element coupled to the second output terminal and the first output terminal, a fourth switch element coupled to the first output terminal and the second output terminal, a first current source module for letting a current passing through the third switch element smaller than a current passing through the first switch element when the first switch element and the third switch element are conducted, and a second current source module for let a current passing through the fourth switch element smaller than a current passing through the second switch element when the second switch element and the fourth switch element are conducted.
