Poor Men's SMU, part 4: Calibration

Posted on do 11 februari 2021 in NLNet • Tagged with PM-SMU

As reported in my previous blog on using the AD5522 SMU development board it was mentioned calibration would be needed to get more accurate low-voltage and low-current measurements.

Procedure

An important aspect of doing calibration is the order in which the parameters are calibrated and what references are used during …

In my previous professional life doing semiconductor process development I used so called source measure units (SMUs) for measuring out transistors. Although I don't remember the exact type number, I guess I had access to a HP 4145A semiconductor parametric analyzer.

Nice thing about these units is that these …
