Kerry D. Wong posted an update on his semiconductor V/I curve tracer we covered previously:
In my previous post, I showed my design of a semiconductor V/I curve tracer and discussed its theory of operation in detail. As promised, I will share some of the test results here. If you have not read my previous article, I would recommend that you take a look at it first.
The prototype was built on three small perfboards. Ideally, you would want build on a properly designed PCB as the excessive wiring introduces some unwanted noise (more on this later). Nevertheless, this is a quick way to build a proof-of-concept prototype.
