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 ...

Current sources are widely used in industrial control systems to transport analog process signals over long distances, but they are less widely used than voltage sources. This post loosely reviews the ...

Current-mode full-wave rectifiers and precision rectification techniques represent vital advancements in signal processing, enabling the conversion of alternating current (AC) signals into a stable ...
