Abstract (en)

[origin: WO2007023159A1] The invention relates to a current source comprising a first switching element (T1), which has a control input (54) and is designed to adjust an output current (I_A) in accordance with a control signal that is received by said control input (54). The current source also comprises a reference resistance (R_S), which is electrically coupled to the first switching element (T1) in such a way that the output current (I_A) flows through the reference resistance (R_S). The latter (R_S) comprises first and second individual reference resistances (R5, R6), which are arranged in series and a diode (D1) that is connected in parallel to the first individual reference resistance (R5). The first individual reference resistance (R5) has a higher impedance than the second individual reference resistance (R6). The power source is equipped with a controller (52), to which a predetermined reference potential (U_REF) is fed and whose actuating signal constitutes the control signal of the first switching element (T1). A second switching element (T2) is configured to supply the controller (52) with an actual value consisting of the voltage across between the first and second individual reference resistances (R5, R6), when the element adopts a first switching position and consisting of the voltage drop across the second individual reference resistance (R6), when the element adopts a second switching position.
