Recently, frequent Design Idea (DI) author Christopher Paul showcased an innovative and high performance true-two-wire current source using a depletion mode MOSFET as the pass device in “A precision, ...

Low-cost, flexible displays that use very little energy could be a step closer, thanks to an innovation that solves a problem that has plagued source-gated transistors (SGT). Low-cost, flexible ...

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 ...
