Abstract
A circuit arrangement for shifting a voltage level comprises a data-current converter () that is connected to a first connection (K) and that has an input for feeding a digital input data signal (DIN), a first output for providing a current (I), and also a second output for providing a reference current (I), and a current-data converter () that is connected to a second connection (K) and that has a first input for feeding the current (I), a second input for feeding the reference current (I), and also an output for providing a digital output data signal (DOUT). Here, a voltage level of the digital output data signal (DOUT) is different from a voltage level of the digital input data signal (DIN). In addition, a method for shifting a voltage level is provided.
