考虑了微加工电感的可能配置。电感可以通过控制坡莫合金磁芯的各向异性来调节磁导率，或者通过图像化的准分布间隙来设置。提出了一种基于简单模型的设计方法。对二次效应进行了分析。给出了一个5mhz降压功率变换器的设计实例。功率密度为12.8 W/cm/sup 2/可实现94%的效率。
Possible configurations for microfabricated inductors are considered. Inductance can be set by adjusting permeability through control of anisotropy of a permalloy core, or via a patterned quasi-distributed gap. A design methodology based on a simple model is proposed. Analysis of secondary effects is also developed. A design example for a 5 MHz buck power converter application is presented. A power density of 12.8 W/cm/sup 2/ is possible for an efficiency of 94%.
