l Continued scaling of electronic device and systems and the increasing demand of circuit functionality require continued scaling of passive components, such as inductors, which typically occupy large area compared to other circuit components. Incorporating magnetic material with on-chip inductor is one of the most researched approaches to increase inductance, quality factor, and silicon chip-area efficiency. These efforts will produce inductors with much higher area efficiency and quality, enabling applications in radio frequency (RF) and analog/mixed signal (AMS) circuit design, such as power amplifier, distributed wireless circuits, low noise amplifiers, high-speed signaling and clocking, which will benefit ultimately the efficient integration for System-on-Chip (SoC) applications. In this presentation, recent efforts on incorporating magnetic materials into on-chip inductor will be reviewed, with particular emphasis on the use of materials such as permalloy (NiFe) and Co-Zr-Ta (CZT). Factors that could affect inductor performance including eddy current loss and ferromagnetic resonance of the magnetic materials will be discussed.
