Multistage amplifiers are essential for driving capacitive loads that span from picofarads to nanofarads in applications such as sensor interfaces, high-speed data converters and power-management ...

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, ...

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 ...

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.

Such cells also need a bulky and expensive signal conditioner to make them useful. Engineers at Loadstar Sensors, Mountain View, Calif. (loadstarsensors.com), use a capacitive sensing scheme in their ...
