Abstract:
This paper presents a comparison of spiral inductors, modeled in ASITIC and Cadence Spiral Inductor Modeler, with inductors form austriamicrosystems 0.35µm CMOS technology. The maximum Q-factor comparison for given shape and dimensions of inductor has been done with two inductors made using normal top metal and two inductors using thick top metal. The obtained results show advantages and drawbacks modeling inductors this way. Despite the limitations, the accuracy of the results that these tools provide makes them useful as a first approximation step in the design of an inductor.
