Spiral inductors have been around for a long time. They are used in wide range of applications ranging from LC tank circuits in filters to bias design for diodes, transistors or oscillators. 5G, and Internet of Things (IoT) devices have created even a greater need for on chip planar spiral inductor design.
This lesson covers the design and simulation steps of an on-chip spiral inductor model using Q3D extractor in Ansys Electronics Desktop (AEDT). It is important to understand the correct workflow of any simulation software tool to perform a simulation. So, this lesson covers the step-by-step simulation procedure of a Q3D workflow and spiral inductor model creation using user defined model (UDM) feature of AEDT.
This lesson shows you how to plot the various results required for analyzing the simulation model. This lesson also shows how to plot various field quantities using Ansys Q3D in addition to plotting the rectangular plots for inductor model.
