Op amps, those versatile building blocks of the analogworld, come in thousands of varieties. Yet there’sstill a need for more and better, in which “better”means units with more desired attributes but ...

If you’ve ever wondered why an op amp has the little plus and minus symbols on it, its because at the heart of it, the device is a differential amplifier. The problem is that — ideally, at least — it ...

Using a complementary silicon-germanium and CMOS technology, Texas Instruments has built a fully-differential op-amp that is optimised for driving high-speed analogue-to-digital converters at up to ...

Op amps played a critical role in knocking out German cruise missiles in WWII. Scientists at Bell Labs came up with a spiffy, high-gain, differencing amplifier. Andy’s still threatening to run SPICE ...

One of my first jobs as a freshly minted graduate engineer involved the maintenance of a set of analogue chart recorders. They were museum pieces by the early 1990s: a motorized roll of graph paper ...
