Patent ID: 7750687

Claim:
Circuit arrangement, comprising: a first level shifter coupled to receive an input signal having a first voltage level from an input terminal, the first level shifter configured to provide a level-shifted signal having a second voltage level higher than the first voltage level, an output stage comprising a first transistor, the first transistor comprising a control terminal operably coupled to an output of the first level shifter and configured to provide at an output terminal of the output stage an output signal based on the level-shifted signal, and a first supply terminal configured to provide a first supply voltage, wherein the first transistor is directly connected to the first supply terminal, wherein the first supply terminal provides a first supply voltage higher than the first voltage level, and wherein a conduction path of the first transistor is arranged between the first supply terminal and the output terminal, a feedback circuit configured to feed back the output signal to the output of the first level shifter.
