Circuits that supply current (using positive current flow convention) are usually known as a current source and one that limits the current flow on the ground side is known as a sink.

CMOS current reference circuits play a critical role in modern integrated circuits by providing a stable and reproducible current source that remains unaffected by variations in supply voltage ...

Note that the inputs of IC1 's remaining unused inverters connect to IC1 's Pin 7 and not to circuit ground per normal practice. Adding an exponential current source eases the task of adjusting the ...

The multi-wire branch is here to stay; so is ground fault protection. But we should unite these technologies only when it’s a good match.

Sensible ground current sensing – or am I an idiot? Trying to get a circuit to sense its own current consumption can be a little tricky. That said, there are plenty of specialist three and four ...

The op-amp current source attributed to Brad Howland of MIT is used widely and is familiar in circuit design. Yet it can be difficult to understand for those not close to it. The following explanation ...

Last time we looked at Spice models of a current sink. We didn’t look at some of the problems involved with a simple sink, and for many practical applications, they are perfectly adequate. Ho… ...

A monolithic current source uses two external resistors to program its output from 0.5 mA to 200 mA with 1% initial accuracy and a low temperature coefficient.
