ABSTRACT:
A voltage drop compensating circuit is disclosed which compensates for unwanted voltage drops along a DC current conductor connected to an integrated circuit. The compensating circuit includes a differential amplifier connected between a voltage supply and the conductor form the integrated circuit which is marred by the voltage drop. One input terminal of the amplifier is connected to the supply lead and an output terminal of the amplifier is connected to the conductor. A feedback network is connected between another input terminal of the amplifier and the integrated circuit. A potential difference between the two input terminals on the amplifier will lead to the amplifier adjusting a potential on the output terminal until the unwanted voltage drop along the conductor is compensated for.
