Abstract
Certain aspects of the present disclosure generally relate to a level-shifting circuit. The level-shifting circuit generally includes a first pull-up path having at least one first diode and at least one first transistor, and a second pull-up path having at least one second diode and at least one second transistor. The level-shifting circuit may also include a first pull-down path having a third transistor and a fourth transistor, wherein the fourth transistor is coupled between the third transistor and the first diode; a second pull-down path having a fifth transistor and a sixth transistor, wherein the sixth transistor is coupled between the fifth transistor and the second diode; and an overvoltage protection circuit coupled to gates of the fourth transistor and the sixth transistor.
