High-Q magnetic inductors for high efficiency on-chip power conversion

View publication

Abstract

We experimentally demonstrate high performance magnetic inductors with Q as high as 17 in the frequency range of 50-250 MHz. These inductors meet target requirements for >90% efficient on-chip power converters. Physics-based models were used to understand magnetic losses, design novel magnetic stacks and innovative processes to achieve high Q.
