The 4-20 mA transmitters used in industrial current-control loops can be implemented as powered current sources, remote non-powered current sinks, or with several other I/O combinations. A useful ...

The circuit in Figure 1 performs active voltage-to-current conversion or acts as a variable-gain current mirror with high precision and bandwidth. A typical application is testing high-speed ICs or ...

The circuit only functions during step-down load transients and operates by rapidly transferring excess load current from the output of the buck converter to its input. Unlike previous unloading ...

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 paper introduces a new FDTD approach to analyze CCCS. The approach is simple to implement and efficient in terms of both computational time and memory usage. The approach can be used to analyze ...

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.
