Abstract: A circuit that includes a level shifter. The level shifter includes a shift path with two transistors coupled in series. The circuit also includes a GIDL detection circuit for detecting GIDL current conditions. The GIDL detection circuit generates a GIDL signal indicative of a GIDL current condition. The signal is utilized to control a voltage of a control electrode of a transistor of the shift path to increase the conductivity of the transistor when the signal is indicative of a GIDL current condition to minimize a GIDL current through at least a portion of the shift path when the second transistor is nonconductive due to the level shifter being in a low power mode.
