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 ...

The LED driver automatically adjusts the output voltage to keep the output current constant and therefore the light output constant. This works with a single LED or with a chain of string of LEDs ...

The LT3954, a DC/DC converter designed to operate as a constant-current source and constant-voltage regulator with an internal 5A switch, is now available from Linear Technology. The LT3954, a DC/DC ...

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 ...

Many embedded systems require a stable, low-noise DC reference. This reference can be a stable current or voltage source. These references are used in many ways. Some typical uses are listed as ...

Certain electromagnetic devices such as differential transformers are effective at translating the displacement of a magnetic armature into an AC voltage, which is a linear function of the ...
