Abstract
In one embodiment, the current source arrangement comprises a current source (B), that has two output terminals () and a control input () to be supplied with a control voltage (Vgs) and is set up to provide a current (I) as a function of a voltage (Vds) at the output terminals () and the control voltage (Vgs), an operating point adjustment unit (E) that is supplied with an actual value (Vi) proportional to an actual value of the current (I) and is set up to provide the control voltage (Vgs) as a function of the actual value (Vi) and a predetermined target value (Iz) of the current (I), and a comparison unit (A) coupled to the control input () of the current source (B) for providing a monitoring signal (), wherein the monitoring signal () is provided as a function of a predetermined limit voltage (VG) and the control voltage (Vgs). A method for operating a current source arrangement is also specified.
