The standard unit of electric current, the ampere, is one of the seven base units in the International System of Units. But measuring a current exactly in amperes is not an easy task. In fact, in 1990 ...
It has long been known that the simple combination of a depletion-mode MOSFET (and before these were available, a JFET) and a resistor made a simple, serviceable current source such as that seen on ...
As power electronics switching techniques advance, there is an increased need to accurately measure current for feedback control and system monitoring. There are several methods to achieve this, and ...
