If you got your start in electronics sometime after 1980 your first project might well have been to light up an LED. Microcontroller projects often light up an LED, too, and a blinking LED is ...

A current source is a critical component in most integrated and discrete circuits and can be described as an electric circuit that generates a steady flow of electrons for a given period of time no ...

A very special circuit was designed to drive the LEDs with a constant current to be used for variety of LED applications. A very special circuit was designed to drive the LEDs with a constant current ...

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 ...

Most of us are used to thinking in terms of voltage sources so there is rarely a day goes by that we do not think about voltage source loading or use Thevenin’s theorem. But what about current sources ...
