Abstract

Level shifting circuits and a related method are disclosed herein. An embodiment of the present invention includes a voltage level shifter, comprising a first pull up transistor coupled to a high voltage signal and a first pull down transistor coupled between the first pull up transistor and a low voltage signal and controlled by an input signal. The voltage level shifter further includes a first bias transistor serially coupled between the first pull up transistor and the first bias transistor. A gate of the first bias transistor is coupled with a bias voltage signal. The voltage level shifter further includes a first additional pull up path coupled with the high voltage signal and a first node between the first pull up transistor and the first pull down transistor, and an output signal associated with the first node. The output signal is a level shifted voltage responsive to the input signal.
