A circuit for level shifting comprises a first and second transistor (A, B), to each of which a signal can be applied, and a third and fourth transistor (C, D). The first and third transistors (C, D) are connected between a fundamental voltage (XUSS) and a supply voltage (XUDD) and have between them a first connection point (O 1 ). The second and fourth transistors (B, D) are connected between the fundamental voltage (XUSS) and the supply voltage (XUDD), and have between them a second connection point (O 2 ). The first connection point (O 1 ) is connected to apply a control signal to the fourth transistor (D) at its control terminal, and the second connection point (O 2 ) is connected to apply a control signal to the third transistor (C) at its control terminal. The circuit is characterized by at least one amplifier circuit (V) to amplify at least one of these control signals.
