ICS Transforms

Not all data can be directly measured. An example would be transconductance of MOSFET devices (the derivative of I_d with respect to V_g). To create a transform, click on the Transform Editor icon.

The Transform Editor window will open with the active setup as the default setup.

To add a transform, type in a name for the transform in the box labeled Transform: and set it equal to the mathematical expression desired. For example:

gm = DIFF(ID,VG)

The available functions are listed in the function box. You can add the variables measured by selecting the appropriate variable name under Vectors. Common constants are also listed.

Once created, click Save. The transform is then listed in the larger box. When you are done adding transforms, click on Done.

Perform the following tests in order:

1. MOS Capacitor

2. PMOSFET

3. pn Diode

4. BJT
