    Abstract: Inductive components, such as transformers, can be improved by the inclusion of a magnetic core. However the benefit of having a core is lost if the core enters magnetic saturation. One way to avoid saturation is to provide a bigger core, but this is costly in the context of integrated electronic circuits. The inventor realized that the flux magnetic flux density varies with position in a magnetic core within an integrated circuit, causing parts of the magnetic core to saturate earlier than other parts. This reduces the ultimate performance of the magnetic core. This disclosure provides structures that delay the onset of early saturation, enabling a transformer to handle more power.

    Abstract translation: 诸如变压器之类的感应元件可以通过包括磁芯来改善。 然而,如果磁芯进入磁饱和状态,则磁芯的好处就会丢失。 避免饱和的一种方法是提供更大的核心,但是在集成电子电路的情况下这是昂贵的。 发明人认识到,磁通磁通密度随着集成电路内的磁芯中的位置而变化,使得磁芯的一部分比其它部分早一些饱和。 这降低了磁芯的最终性能。 本公开提供延迟早期饱和的开始的结构,使得变压器能够处理更多的功率。
