利用引线框架对磁耦合通信链路的噪声消除
摘要：
一种集成电路封装件，包括包封部和引线框架，所述引线框架的一部分被布置在所述包封部内。所述引线框架包括形成在所述引线框架中的第一导体，所述第一导体具有基本被布置在所述包封部内的第一导电环路和第三导电环路。第二导体形成在所述引线框架中，与所述第一导体电流隔离。所述第二导体包括第二导电环路，所述第二导电环路基本被布置在所述包封部内靠近所述第一导电环路，以在所述第一导体与所述第二导体之间提供通信链路。所述第三导电环路以相对于所述第一导电环路的相反的方向卷绕在所述包封部中。
摘要（英）：

An integrated circuit package includes an encapsulation and lead frame with a portion of the lead frame disposed within the encapsulation. The lead frame includes a first conductor formed in the lead frame having a first conductive loop and a third conductive loop disposed substantially within the encapsulation. A second conductor is formed in the lead frame galvanically isolated from the first conductor. The second conductor includes a second conductive loop disposed substantially within the encapsulation proximate to the first conductive loop to provide a communication link between the first and second conductors. The third conductive loop is wound in an opposite direction relative to the first conductive loop in the encapsulation.
