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 ...

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 ...

Previous installments of this article series discussed the need to verify SPICE model accuracy and how to measure the output impedance, small-signal bandwidth, and input-referred errors of operational ...

Modern operational amplifiers (op amps) and instrumentation amplifiers (in amps) provide great benefits to the designer, when compared with discrete semiconductors. But all too often, some very basic ...

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 ...

This IFD describes a single op-amp voltage indicator that lights LEDs to indicate the input voltage’s relationship to two thresholds. Green indicates input above the top threshold, red the input below ...

50 years ago a young Brit joined Fairchild where he was to design one of the most famous ICs ever made – the 741 op amp. Dave Fullagar had been working for the RRE and answered a Transitron ad. Tom ...
