There are various reasons why you might need to split a voltage rail in your design. Perhaps the design contains a sensor or an IC that requires a bipolar supply, or you need to make the best use of ...

The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...

The operational amplifier, or op amp, is one of the most basic building blocks used in analog circuits. Ever since single-chip op amps were introduced in the 1960s, thousands of different types have ...

Of digital electronics, a wise man once said that “Every idiot can count to one.” Truer words have rarely been spoken, because at the end of the day, every digital circuit is really just an analog ...

Taking apart a circuit board or module and reconstructing its complete schematic is a valuable skill. We can see how someone designed circuitry to gain ideas that can be applied to our work. And ...

Op-amp performance is disrupted by EMI in a variety of ways. Reducing EMI in amplifiers using filters. How to mitigate EMI in Class-D audio amps. In this article, electromagnetic interference (EMI) ...
