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.

Today’s operational amplifiers in a few ICs can replace a rack of those tube units and are far more electrically quiet, not to mention being more power efficient by several orders of magnitude.

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 ...

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 ...

Sponsored by Texas Instruments: Special op amps are available to deal with drift, high- and low-input voltages, noise, and error sources in critical applications such ...

With both current and voltage feedback operational amplifiers (op amp) available to the system designer, how do you decide which one to use? This article is the second of two parts. It reviews several ...

You think of op amps as amplifiers because, no kidding, it is right in the name. But just like some people say, “you could do that with a 555,” [Doctor Volt] might say, “you can d… ...

Research from all publishers Recent studies have focused on refining the design and operational frequency of memristor emulation circuits to meet the demands of modern integrated systems.
