<p>The invention solves a problem of compensating an unwanted voltage drop along a DC current conductor (10) connected to an integrated circuit (20). The inventive apparatus comprises a differential amplifier (106) connected between a voltage supply (105) and the conductor (10) from the integrated circuit (20) which is marred by the voltage drop. One input terminal (103) of the amplifier (106) is connected to the supply lead (105) and an output terminal (109) of the amplifier (106) is connected to the conductor (10). The feedback network (51) is connected between another input terminal (104) of the amplifier (106) and the integrated circuit (20). A potential difference between the two input terminals (103, 104) on the amplifier (106) will lead to the amplifier (106) adjusting a potential on the output terminal (109) until the unwanted voltage drop along the conductor (10) is compensated for.</p> |
