Abstract (en)

The arrangement has a cascode circuit with two metal oxide semiconductor (MOS) transistors (12, 14), where a series connection of a load (10) lies between supply terminals (20, 22). The transistors have load lines that are switched in series, and a control line (17) that is connected with the load. The control line is switched at a provided gate potential, where the gate potential is variable and is provided by a control circuit (R). The control circuit provides the gate potential in the control line, such that the current is kept constant by the load over the transistor (14).
