Octagonal inductor with patterned earth shield

questex06.in : Octagonal inductor with patterned earth shield

Requires: QUEST Minimum Versions: QUEST 2.0.2.R

This example is an octagonal inductor. To load and run this example, select the Load example button in DeckBuild. This will copy the input file, GDSII file and results to your current working directory. Select the run button to execute the example.

The GDSII file can be viewed in MaskViews, Expert or any other Layout editing tool that can read the GDSII format. The process is a generic process using six metal levels and standard values for conductivity and permittivity.

Since the inductor in this example has a diameter of approximately 300um, the depth of the substrate in the simulation was chosen to be 400um. A grid is below the inductor.

A two port simulation is defined. The first port is between the electrodes "in" and "gnd1". The second port is between the electrodes "out" and "gnd2". The reference electrodes "gnd1" and "gnd2" are on the grid below the inductor.

All the results will be placed in a directory structure under the name "questex06_db" which was defined with the SAVE command.

Three dimensional structure files can be viewed with TonyPlot3d. All other RLCG and Q versus frequency data can be viewed with TonyPlot.

This example can be compared with the examples 'questex04', 'questex05' and 'questex07' because this is the same inductor, but in the other examples the inductor is alone or a plate is below the inductor or a pattern is around the inductor.

In this example (inductor with a grid) the Qfactor is high and the resistance is constant since the current return path is always through the grid.
