If you are an electrical engineer and haven’t checked out any of the app notes written by Jim Williams you are missing out!
Unfortunately, Linear Technology was bought out by Analog Devices in the last year or two and his app notes are much harder to find! The old Linear Technology website had a page with links to every app note written by Jim, the Analog Devices website has no such page. They still appear to be available on Google though, and Kent Lundberg has compiled a bibliography of his works.
Sometime it might be a good idea to compile all of these app note PDFs into one place again, but for now I’m glad that Kent Lundberg at least has a record of the names of each one.
