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 ...

A simple extension of a previous class A/B differential output amp DI that creates a square-law characteristic.

This design idea reprises another “ 1A, 20V, PWM controlled current source.” Like the earlier circuit, this design integrates an LM3x7 adjustable regulator with a PWM DAC to make a programmable 20 V, ...

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.

Researchers at the US Department of Energy’s Oak Ridge National Laboratory (ORNL) say they have developed medium-voltage ...
