In previous articles—Common op-amp circuits, Op amps do integration, and The practical op-amp differentiator is quite versatile—we looked at some classic op amp circuits. These circuits used negative ...

A while back, [Chris Lu] was studying how analog circuits, specifically op-amps can be used to perform mathematical operations and wondered if they could be persuaded to solve differential equations, ...

Modeling the performance of an analog device with SPICE is one of the standard techniques used by circuit designers to perform initial characterization and performance analysis before putting together ...

A few months ago, I wrote a Signal Chain Basics article titled “3 considerations when selecting an op amp.” While that article is very useful for selecting operational amplifiers (op amps) for new ...

Modern op amps have much higher operating bandwidths than their predecessors. These new devices are excellent building blocks that can greatly simplify the design and construction of high-bandwidth ...

A continuity tester, as found on most multimeters today, is a great tool for finding broken connections and short circuits. But once you’ve found a short, it’s up to you to figure out which part of ...
