Making a Measurement

You measure the device under test (DUT) by using the measurement circuit as

shown in the following diagram. SMU2 and SMU3 sweep the same voltage to the

gate and drain. SMU3 measures the drain current (Id). The source and substrate are

connected to circuit common.

You should get result similar to the following figure. Gate voltage Vg (swept from

0 V to 2 V) is assigned to X axis, ÖId

is assigned to Y1 axis, and ¶ÖId / ¶Vg is

assigned to Y2 axis.
