Patent ID: 6930622

Claim:
A voltage level converter device for the conversion of an input signal, which is at a first voltage level, into an output signal, which is at a second voltage level that differs from the first voltage level, the voltage level converter device comprising: a first and a second output transistor connected in series, whereby the output signal is output at an output of the voltage level converter device provided between the first and the second output transistors; a third transistor having a control gate which is connected to the output of the voltage level converter device, and a source-drain current path which is connected to a control gate of the first output transistor; a fourth transistor having a source-drain path which is directly connected between corresponding control gates of the first and the second output transistors, and which is further connected between the first transistor and an input of the voltage level converter device, whereby an additional transistor is connected to the source-drain current path of the third transistor to be switched on or off when switching over the output signal, and the additional transistor, which is under control of a control signal comprising a voltage level corresponding to the voltage level of the input signal, is switched on or off for switching on or off the current path.
