  • Patent number: 6366036
    Abstract: In an arrangement for coupling out an output current from a load current by a load (2), particularly a deflection coil of a cathode ray tube by means of an output resistor (4), which arrangement comprises an output current mirror (9, 10, 11), in which a control value in the form of the difference between two voltages dropping across two resistors (35, 36) for controlling the load current is generated and in which a reference current bank (12) is provided with a current mirror circuit whose input receives a constant current for generating constant currents, a minimal temperature dependence is obtained in that the output current is coupled to the emitter of at least a first output transistor (10) and at least a second output transistor (11) of the output current mirror, in that the reference current bank (12) supplies a first reference current which, together with the output current, is coupled to the emitter of the first output transistor (10) and the second output transistor (11) of the output current mirror,
