Abstract

Driver circuits to invert an input signal and to generate an output signal based on the inverted input signal are presented. The voltage level of the logical high value of the output signal is adjustable. The driver circuit has a high side switching element coupled between a supply terminal and the output terminal of the driver circuit. The driver circuit has a low side switching element coupled between the output terminal of the driver circuit and a reference potential. The driver circuit has a regulation transistor, wherein a controlled section of the regulation transistor is coupled in series with the high side switching element and the low side switching element between the supply terminal and the reference potential. The driver circuit has a feedback circuit to regulate the output voltage by generating a regulation voltage at a control terminal of the regulation transistor.
