Abstract

A level shifting circuit that includes a level shifter and a circuit stage. The circuit stage includes a pair of diodes circuits. The circuit stage includes a first output node and a second output node. The first output node is coupled via a current path to a first output of the level shifter and the second output node is coupled to via a current path to a second output of the level shifter. One of the diodes is coupled to the first output node and a power supply terminal. The other diode is coupled to the second output node and the power supply terminal.
