UAIPD 15-0011 describes Dr. Yang-Ki Hong's invention of a GHz magnetic chip inductor with high magnetic loss. The inductor uses both air-core and magnetic-core materials, with a center magnetic bar surrounded by coils and top/bottom magnetic slabs enclosing an air-core inside. This combination realizes simultaneously high inductance, high Q factor, and high self-resonant frequency by reducing core loss. The technology outperforms conventional air-core and magnetic-core inductors.
