Ultra-low loss integrated magnetics platform for high frequency power delivery networks
No Thumbnail Available
The future smart systems are envisaged to continue shrinking in size and weight, while integrating more features and functionalities, leading to significant increase in power density and efficiency requirements. In addition, devices such as mobile phones and tablet computers require a large reduction in electronic component height. While SMT chip power inductors may have thicknesses as low as 0.6mm; thin film power inductors offer an incremental height of ~50μm. This paper introduces an ultra-low loss integrated magnetics platform for the next generation power systems on-chip (PwrSoC) and in-package (PwrSiP) applications. The integrated magnetics-on-silicon inductors and transformers have been designed, fabricated using conventional CMOS fabrication processes, and characterized, demonstrating industry leading performance metrics.
