In 2008, Bob Pease exchanged e-mails with Linear Technology’s Mark Thoren, me, and a few other friends. The subject was how an amplifier will oscillate if you put a capacitive load on it. Bob knew ...

In olden days, when op amps used ±15 V supplies and input/output signals were ±10 V, we had few problems with input/output limitations. Our op amps output impedance (Zo), small-signal AC impedance, ...

Modern high-frequency amplifiers are a cranky group that lose performance when driving capacitive and reactive loads. Fortunately, you can use some simple tricks to pacify poorly loaded amplifiers.

Op amps are generally pretty easy to apply, but there are some practical nonideal behaviors you have to keep in mind. [EEforEveryone] takes a test board with some 2X amplifiers on it and — after some ...

The DS-2100 and the DS-2100 WiFi displays from Loadstar Sensors Inc. are load indicators designed to work seamlessly with the company's patented capacitive load sensors. The DS-2100 and the DS-2100 ...

. The data can be imported to a PC with an RS-232 or 802.11b wireless connection. The displays work with Windows XP-based software that lets users calibrate the sensors, show individual and total ...

Most load cells on the market use a cantilever outfitted with strain gages to measure loads. Such cells also need a bulky and expensive signal conditioner to make them useful. Engineers at Loadstar ...
