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 ...

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 the ...

This isolated current regulator produces currents up to ±10 A, depending on load configuration, with current determined by the tap chosen and a 0- to 1-V control voltage V ISET. When measuring the ...

Nullator, norator, and nullers all started out as theoretical circuits. A nuller is the result of the combination of a nullator and a norator, which forms a network element with a transmission matrix ...
