The effects of Substrates (Variable Substrate)

This section is designed to allow users to understand how changing the substrate will change the saturation current of a MOSFET.

Instructions:

You can use the tabs at the top of the window to navigate quickly between pages. Click on the blue dots to open a pop-up window to select a particular Substrate. Then click on the "Simulate" button at the bottom right hand of the window.

To plot results for another Substrate, click on the "Input" button to go back and adjust the input parameters. In the simulation tab, to see all curves simultaneously, click on the "All" button at the bottom left hand of the window.

To find out which curve corresponds to each substrate, you can click on the white scroll bar at the bottom of the window to find the corresponding legend. This will allow you to compare the different Drain Currents most effectively.

So how does changing the substrate affect the saturation current of a MOSFET?
The following simulation will give you a better idea of how everything is related.
