摘要
This letter presents an analytical formula for the inductance of an inductor with the layout of variable metal width, based on the quasi-static approximation. Experimental results indicate that the analytical formula is feasible. A layout with metal whose width increases a monotonously from the inner turn has a higher Q value than other configurations of the metal with the same inductance. This information will be help in designing high-performance inductors for RF integrated circuit applications.
