Historically, researchers impaled giant squid, snail, and frog axons with electrodes to study nerve function by measuring ion channels. Today, electrophysiologists have enhanced their ability to ...
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 ...
The ever innovative and prolific Mr. Woodward has offered “PWM-programmed LM317 constant current source,” an intriguing programmable constant current source which elicited a lively conversation in its ...
