Inductor current can't be suddenly cutoff if no freewheel diode is attached

Somebody asked me the other day about current regulator diodes and why they were not used more frequently for LEDs (to make them work over a wide range of voltages). I explained they were basically JFETs with the gate tied to one end, and added that depletion mode MOSFETs could be used too, to much higher voltages, but I'd never seen one so used. Finish up, go to SED, and there it is. Showed him, and LOL'd.

I love to cook with wine. Sometimes I even put it in the food.
Interesting.
Thanks.
There used to be page charges for these journals. Looks like they don't sell RSI in print any more, so they have that new pricing model. They charge either the subscribers and the occasional reader, or the author.

They do show up from time to time, but the peer review process misses other errors as well. I've had comments published criticising circuit design, bu t I've also published criticisms of authors' grasp of the literature, which is a more serious fault in a scholarly journal.
In fact you don't have to, and never did. Paying the page charges got you r eprints.

The pages charges were never obligatory. I never paid a cent to get any of my comments published, and the first one was back in 1972.
