Zero-drift operational amplifiers have proven to be valuable problem solvers due to their low input offset voltage and minimal input offset voltage drift. Rail-to-rail input versions of these ...

Amplifier circuit offsets are always an important topic for any amplifier design. Most voltage amplifier circuit offsets are a result of the amplifier’s input voltage offset, input bias current and ...

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.

The switching amplifier, or class D amplifier, has risen quickly to prominence in consumer audio applications, from MP3 devices including mobile phone handsets to games consoles, LCD-TVs, and home ...

I'm researching preamp-amp matches and due to lack of information on the Internet am left with a question regarding output/input differences between balanced and unbalanced feeds. The contemplated ...

This article started because a good friend of mine dropped a Panasonic SA-XR50 switch-mode amplifier to me for some basic bench test. This article will NOT be a review of that unit, but an ...

It is hard to imagine a time without active amplification. However, if you go back far enough, radio communications started in an era where generating RF required something like a spark gap and ...

It’s no surprise then that one of the first specifications a novice or seasoned enthusiast looking to buy an AV receiver or amplifier sees is its power output ratings. After all, it’s among the most ...
