Multiple SMU stability considerations
Using two or more SMUs to test an active device, such as a field-effect transistor (FET) or bipolar
junction transistor (BJT), can aggravate system stability. The next figure shows an example of BJT
characterization curves determined under stable conditions.
Figure 493: Effects of oscillation on test data: Without oscillation
The next figure shows an example of what can happen to a BJT characterization curve when the
system oscillates.
