Embodiment Construction

[0019] figure 1 A schematic block diagram of an integrated circuit 10 is shown, which is realized as a layer structure on a semiconductor crystal not shown in detail. Through the structuring of different layers on the semiconductor crystal, it is achieved in figure 1 The different functional areas are shown very simplified in . The selected diagrams are only used to explain functional interrelationships and are not to be interpreted as images of semiconductor layout designs.

[0020] The integrated circuit 10 has a plurality of bonding pads 16 which are provided as contact surfaces for mounting bonding wires (not shown). The electrical coupling of the integrated circuit 10 to a circuit board / printed circuit, not shown in detail, can be effected by means of bonding wires. A plurality of reference potential arrangements 12 are formed on the integrated circuit 10 and are provided for supplying an electrical reference potential to the terminals 18 . The terminal 18 is realized...

Abstract

The invention relates to an integrated circuit (10) comprising at least one connection (18) for incoupling and / or outcoupling electrical signals, especially data signals, and integrated reference potential means (12) associated with the connection (18) to provide an electrical reference potential on the connection (18). The invention is characterized in that the reference potential means (12) are configured to be switchable, especially by way of an overmodulation. The invention also relates to the use of the integrated circuit for semiconductor components.

Description

technical field [0001] The invention relates to an integrated circuit having at least one terminal for coupling in and / or outcoupling electrical signals, in particular digital signals, and an integrated reference assigned to the terminal for supplying the terminal with a reference potential Potential device. Background technique [0002] A commercially known integrated circuit is implemented as a semiconductor component and has a large number of internal and external terminals. The internal terminals are configured as nodes of electrical leads between individual circuit elements implemented in the circuit, such as resistors, capacitors or transistors. The external terminals are implemented as electromechanical interfaces that connect the integrated circuit to a printed circuit or other electrical component, usually through bond wire connections or solder ball connections. In order to ensure proper functioning of the integrated circuit, it is desirable for each terminal to ...
