Abstract
A level shift circuit includes: a first transistor coupled to a first reference voltage for receiving a first voltage input signal; a second transistor coupled to a second reference voltage; a first diode-connected transistor coupled between the second transistor and the first diode-connected transistor; a third transistor coupled to the first reference voltage and the second transistor, for receiving a second voltage input signal, wherein the first voltage input signal is an inverse version of the second voltage input signal; a fourth transistor coupled to the second reference voltage and the first transistor; a second diode-connected transistor coupled between the fourth transistor and the third transistor; and a fifth transistor coupled to the second voltage input signal, the first reference voltage, and the fourth transistor, wherein a level-shifted output signal corresponding to the first voltage input signal is generated at an output node of the fourth transistor.
