Closed-loop current sensors employ a feedback control circuit to provide an output that is proportional to the input. Compared to open-loop sensors, this closed-loop feedback design inherently provides enhanced accuracy and linearity as well as better temperature drift compensation and resistance to ...
Therefore, it is normal to use a current amplifier that produces a voltage output that is proportional to a current input, with (nominally) no voltage drop between the input terminals. Because of the latter property, the device is normally called a zero resistance amplifier (ZRA) in the ...

resistance 84. Thus, the rectified wave from the rectifier bridge 56 at less than a 100% duty factor amounts to a doubled frequency direct voltage pulse train and the resulting direct current is applied to the load circuit, ripple in the current being minimized by the high L/R of the ...
Most known are Hall, magneto-resistance, and fluxgate sensors. In a simple design, all of them are inserted into a single core, while the later fluxgate exists in more sophisticated versions, such as dual-core and tri-core. Closed-loop methods minimize the non-linear effects of the magnetic...
An auxiliary current transformer circuit adapted to carry current proportional to that in the branch is connected to an intermediate point in the pilot circuit, the two circuits in parallel across which the auxiliary current transformer circuit is connected being of substantially equal resistance. As ...
The flow configuration of ions in forward potential bias assures that the double layers do not overlap, and thus the resulting electrical resistance reduces significantly. At the reverse bias, the cations are forced to flow towards the convergent end of the nanopore, and these cations get ...
