The compliance range for operating voltage extends from a minimum of 4 V (both circuits) to a maximum that is slightly lower for the Figure 1a circuit (90 V), because of its different output device.

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. One challenge in circuit design is ...

Take advantage of current control topologies without self-heating error while retaining the 317/337's fault protection ...
