Abstract

Optimal design of passives is important for realization of monolithic dc-dc converters. This paper discusses ideas for integrating inductors onto a silicon chip. Expressions for trace resistance and inductance estimation of on-chip spiral inductors will be compared. Based on these expressions, planar spiral inductors will be designed for use in monolithic dc-dc buck converters. An out-of-plane technology that uses a surface micromachining technique, known as plastic deformation magnetic assembly, is used to erect high quality inductors with small footprints. Experimental results from buck converters with each inductor are presented.
