A tough challenge for test engineers is explored in terms of test methods, pitfalls, and measurement errors. For the test engineer, RF and microwave power amplifier testing imposes unique challenges.

Let’s say that for a project you are working on, you need an op amp (of course, I would like it to be one of one of Touchstone’s op amps), and you want to make sure that the amplifier meets your ...

Figure 1. Use the circuit in (a) to measure input bias current on the op amp’s noninverting input. Adding a loop amplifier in (b) keeps the op-amp stable for measurements on the inverting input. The ...

Google announced that its AMP and mobile-friendly test tools both now support the ability to edit code and rerun the test, live. So if you want to make changes in its code editor to see how it will ...

There has been a lot of controversy on many of the Internet forums regarding power capability of receivers when driving multi-channel speaker systems. Some argue that when a receiver is rated at ...

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 ...
