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 ...

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 ...

Author Mazi Hosseini describes a simple, low-cost, voltage-controlled current source using two op amps that provides a good range of current and maximum load. One challenge in circuit design is ...

The LM334 is not only an adjustable current source, but it is also a rectifier. Right on the front page of the TI data sheet are the words: “Reverse applied voltages of up to 20V will draw only a few ...

Engineering labs are usually equipped with various power supplies, voltmeters, function generators, and oscilloscopes. One piece of equipment missing from many such labs, however, is a current source.

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 ...

It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how ...

065TSMC_RS_03 is a reference current and voltage source (RS), used to supply analog blocks. It is based on bandgap reference voltage source, forming t ...
