An amplifier has a function to increase an input signal by amplification factor of amplifier for outputting. Electric / Electronic circuit uses voltage and current in the main for input signal and ...

This is a quick tutorial about making a practice amp for a guitar. Very quick. And dirty. In fact, it sounds remarkably dirty. The amp is made from some junk I found in my basement, along with two op ...

Op amps are the basic building blocks for much of linear circuit design. You probably learned about them in college and even designed some products containing an op amp. As an electronic engineer, you ...

Here are four examples of op amp models (schematics and symbols). There's variety of ways to model behaviors, these are simply four possible approaches. Copy and modify them anyway you like. Over the ...

How do you get the input of an op-amp to work below the negative-most supply rail?, I asked. Now I know – thanks to the patience of ADI field application engineer Andreas Koch. It was not just any ...
