If you connect three voltage sources in parallel to one terminal of a DUT witheach operating at near-maximum current and the DUT is in a high-impedancestate, then all current will go to the voltage ...

Many process-control sensors, such as thermistors and strain-gauge bridges, require accurate bias currents. By adding a single current-setting resistor, R 1, you can configure voltage-reference ...

The source voltage sees a light load and produces an output voltage that can supply more current than the original source. Same for a current mirror.

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 ...

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.

A current source provides electrical energy with a constant current. The implication is that if the resistance of the load changes the current source will vary the voltage to compensate.
