If you have read my first blog, you may have noticed that I really like op amps. My primary expertise lies in designing them, but I’m also intrigued by clever op-amp application circuits. To promote ...

We took a look at op amp integrators in the previous article, Op amps do integration, so it makes sense to round out the picture by covering differentiator circuits. Of course, differentiation is the ...

Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with our op amp quiz; answer explanations are included. By 1969, a fledgling ...

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 ...

My hands-on introduction to operational amplifiers was in 1969 while in the army as a junior scientist in the Atmospheric Science Laboratory at the White Sands Proving Grounds. We had taken a ...
