Guest columnist Dale Cigoy, lead applications engineer at Keithley Instruments, outlines how an understanding of the challenges for testing capacitors can be invaluable to engineers. Capacitors are ...

Analog guru Bob Pease dropped me a line referring to the recent Design Idea on testing capacitor leakage. Bob, being pretty well versed in this subject was a little peeved. He wrote: You probably ...

First, we need to consider how far within the direct current leakage (DCL) limit the typical part will be. Unlike the range of capacitance values in a given lot, which have a normal distribution, most ...

Members can download the PDF ebook. We all know that capacitors have a shunt resistance (leakage) and that leakage resistance should be pretty easy to measure, right? Wrong! I've measured a lot of ...

A while back, I mentioned 1 that we needed a clean test fixture to measure an operational amplifier's input current in the low femtoampere region. But aside from a neat little integrating capacitor ...
