The circuit shown in Figure 2 depicts what looks like an op amp with a simple MOSFET (you can use bipolar if you wish) buffer on the output. Feedback is taken from the MOSFET sources from a grounded ...

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 ...

Linear Technology's recently introduced LT3092 is a 2-terminal programmable current source, typically defined as a circuit that delivers or absorbs current.

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 ...

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… ...

If you need a current source, and you don’t know where to look, it is not easy to find advice on how to make them.

Over on his YouTube channel [Aaron Danner] explains biasing transistors with current sources in the 29th video of his Transistors Series. In this video, he shows how to replace a bias resistor (and… ...

Therefore, a current source circuit is used to increase the write current in a sloping manner, and write completion is detected by monitoring the write voltage with a voltage detector circuit to ...

Announced yesterday, researchers from Surrey and Cambridge universities and the National Research Institute in Rome have used thin-film source-gated transistor (SGT) to create compact analogue circuit ...
