This circuit produces a regulated current in a load, the range of which is determined by the tap chosen. The current value within that range is set by a control voltage.

Demand for voltage-controlled current sources (VCCSs) and multipliers in a wide spectrum of electronics and communication devices always seems to exist. The multipliers employed in circuits like ...

This article explores several approaches for using FETs in voltage controlled circuits.

I can also vary the base voltage and control the amount of current through the LED or other load devices. However, for some loads, even this circuit might be an improvement over a simple resistor.

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 ...

Thus the inductor acts like a voltage-controlled current source. Current shares evenly just by connecting all the current control signal pins together.

It was based on a constant current source that is controlled by a DAC hooked up to the Arduino. By measuring both the resulting voltage and current of the load, the system can dynamically adapt to ...
