Here is a close look at the common- versus differential-mode voltage and instrumentation amplifier (IA) topologies.

A Class D audio amplifier is basically a switching amplifier or PWM amplifier. There are a number of different classes of amplifiers. We will take a look at the definitions for the main ...

Though sometimes taken for granted, designers shouldn’t overlook the intricacies of voltage- and current-feedback op amps—integral players in the analog and mixed-signal worlds. Op amps amplify tiny ...

As you can see, there are a number of variables and the answer is simply not that straight forward. When conducting amplifier measurements, we tend to be a bit more forgiving with receivers than multi ...

Most everyone that has ever purchased an external amplifier is at least familiar with the term voltage gain. Simply, it is the degree to which an amplifier actually ...

While we like the idea of plug-and-play set-ups as much as anyone, there’s more to getting the best out of stereo amplifiers than simply powering them up on a hi-fi rack, plugging in speakers and ...
