Semiconductor component comprising a counter signal for preventing crosstalk between electronic subassemblies |
摘要 |
<p>A semiconductor component including a first integrated circuit in a substrate which is adapted to produce electrical signals with a high-frequency signal component, wherein the substrate is such that the high-frequency signal component can propagate on a substrate surface and/or in the substrate interior, a second integrated circuit in the same substrate which is such that its function can be compromised by high-frequency signals, and a countersignal circuit in the same substrate which is adapted to deliver an electrical countersignal which at least at a selected location of the substrate surface and/or the substrate interior attenuates or eliminates the high-frequency electrical signal component emanating from the first integrated circuit, wherein the countersignal circuit includes a receiver which is adapted to produce an electrical signal dependent on the instantaneous field strength of the high-frequency signal component, and a shielding transistor provided in the substrate and having a control electrode and a first field electrode and a second field electrode, whose control electrode is connected on the input side to the receiver and whose first and second field electrodes are acted upon with a predeterminable first and second electrical potential.</p> |
