A DEVICE FOR CONTROLLING A CURRENT TO A LOAD (98) BY MEANS OF MIRRORING IS DESCRIBED. TWO TRANSISTOR UNITS (60, 70, 91, 92) ARE CONNECTED TO A COMMON REFERENCE POINT (PREF). BY DRIVING A CURRENT THROUGH ONE OF THE TRANSISTOR UNITS (60, 70, 91, 92), A CORRESPONDING CURRENT IS GENERATED IN THE SECOND TRANSISTOR UNIT (60, 70, 92). A CONTROL UNIT (95), CONNECTED BETWEEN THE TRANSISTORS CAN REGULATE A VOLTAGE DIFFERENCE BETWEEN TRANSISTORS. ACCORDINGLY, THE SIZE OF THE LOAD (98) ATTACHED IS DETERMINED THROUGH MIRRORING WITH ACCURACY AND MINIMAL POWER LOSS. (FIGURE 9)
