Abstract

An electronic device comprising a level shifter and a method. The level shifter includes an input adapted to receive an input signal switching between a low input voltage level and a high input voltage level and a first switch and a second switch coupled in series between a low output voltage supply and a high output voltage supply. An output is coupled to an interconnection node between the first and the second switch and is adapted to be coupled to a load. The first and second switches are controlled by the input signal. The level shifter further includes a third switch which is coupled between the interconnection node and an auxiliary voltage supply which has a voltage level between the low output voltage level and the high output voltage level.
