ABSTRACT:
A level converter for providing an output signal at a circuit output based on an input signal includes an output coupling circuit formed to provide an output signal based on a first partial output signal and a second partial output signal, a driver circuit formed to provide the second partial output signal such that the second partial output signal is switchable between two different signal levels depending on the state of the input signal, wherein an input of the driver circuit is capacitively coupled to the input of the level converter in order to allow for switching between the signal levels of the second partial output signal by the capacitive coupling in response to a change in the state of the input signal, and a holding circuit formed to keep the state of the second partial output signal constant in case of a constant state of the input signal.
