Abstract
In this paper, we proposed planar spiral inductors based on AC coupling for high-frequency wireless signal transmission. Design and characteristics of various structures of the inductor were analyzed. Capacitance between the inductors can be reduced by positioning two thin-film inductors in parallel. So two structures were proposed. First structure is inter-diagonal structure. This structure was made not to overlap the wire part of the paralleled two inductors. Second structure is On-chip type structure that the two thin-film inductors were in parallel but located on diagonal line not to face each other. The resonance in this structure was reduced from twice to once by increasing horizontal distance between the two thin-film inductors, because the capacitance effect between the two thin-film inductors decreases when the distance between the two inductors increases.
