If you’re designing a linear circuit of any kind today, it most likely involves an op amp and even an analog-to-digital converter (ADC). The op amp is your go-to device simply because it can be ...

After my last Signal Chain Basics article, The basics of op amp loop-stability analysis: A tale of twin loop-gains, I received questions about how to generate the open-loop SPICE simulation curves ...

Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having to ...

Maybe you are familiar with the op-amp as an extremely versatile component, and you know how to quickly construct a huge variety of circuits with one. Maybe you even have a favorite op-amp or two for ...

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 ...

When it came time to test the lab prototype described in part 1, I realized that I had no signal generator with enough output voltage swing of any waveform to exercise the circuit. I have generators ...
