FET constant current sources use JFETs and MOSFETs to deliver a load current, which remains constant despite changes in load resistance or supply voltage. A FET constant current source is a type of ...
Testing power supplies and batteries requires current loads capable of sinking large current and dissipating substantial amounts of power. A simple but accurate current load can be built using just a ...
Download this article in PDF format. High-brightness visible-light LEDs (VLEDs) require a constant-current source. This simple, RFI-free circuit takes advantage of the normally-on properties of the ...
