Abstract

Novel vertical tapered solenoidal inductors were designed, fabricated and analyzed in this paper. Due to vertical tapered solenoidal structure, the proposed inductor has small interwire capacitance between adjacent turns and overlap capacitance between the spiral and underpass, which can increase the self resonance frequency of the inductor significantly. The spacing between adjacent turns of this inductor can be minimized to zero, which can save precious physical area on IC boards. For a compact structure, the proposed inductor also has higher inductance as compared with the normal spiral inductor of the same outer and inner dimensions
