Current-feedback amplifiers have a higher slew rate than do voltage-feedback amplifiers. As such, current-feedback amps can better solve high-speed problems than their voltage-feedback counterparts.

Voltage-Feedback operational amplifiers (VFA op amps) allow circuit designers to swap gain for bandwidth. current-feedback op amps (CFAs) are simpler to use than VFAs, but do not offer gain-bandwidth ...

Assuming that they're in series, 6v nominally for alkaline, as low as 4.8 for NiMH. Batteries are specced in Amp-Hours, not amps--amperage is a rate, Ah is a quantity indicating the amount of energy ...

Author Mazi Hosseini describes a simple, low-cost, voltage-controlled current source using two op amps that provides a good range of current and maximum load. One challenge in circuit design is ...

A team of researchers in France has found that applying a voltage across a 100-nm-thick cylindrical soap film causes the fluid inside it to flow upwards. If the voltage is increased, the film thickens ...

One of the most important specifications of an op amp is its input-offset voltage. You can null out this voltage on many op amps, but the problem with determining the input-offset voltage is that the ...

Abstract: Electrospinning is a simple and cost-effective method for producing smooth and thin nanofibers. The relationship between experimental parameters and the properties of the obtained fibers is ...
