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 ...

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 ...

Significant efficiency and performance improvements can be realized by improving the current loop’s power supplies, replacing linear regulators with high-efficiency buck regulators. It also increases ...

TAMPA, Fla. (WFLA) — The Gulf Loop Current is a large pool of hot water a couple hundred miles west of Tampa Bay. This hurricane season, it’s looking even more imposing than normal. The loop current ...

The term hot loop is relevant whenever switching regulators and their electromagnetic compatibility (EMC) are involved. This topic especially comes up in the optimization of trace routing on printed ...

Single-phase power factor correction (PFC) circuits—a kind of front-end AC/DC converters—are ubiquitous in a variety of consumer electronic devices, including laptop adapters, LED driver power ...
