This Design Idea is a two-wire current regulator that strikes a good balance between performance and parts count. Employing three transistors, three resistors, and one LED, it achieves good regulation ...

Over on his YouTube channel [Aaron Danner] explains biasing transistors ... a narrow voltage range, which is generally good enough, but not as good as a true current source.

When you connect the gate to the source of a JFET (junction field-effect transistor), it becomes ... of the JFET will determine the rough range of the current, but it does change over temperature.

I take my hat off to engineers that know transistors in every ... particularly as the output is a current source. The linear brief suggests: If used in oscillator or function generator circuits, an ...

Recent technological advances have enabled the development of a wide range of increasingly sophisticated wearable and ...

Toshiba has launched the TBD62783A series of highly efficient transistor arrays, said to be the industry’s first with a DMOS FET type source ... current drive with absolute maximum rating of the ...

The transistors are made of silicon, metals like gold and copper, and insulators that together take an electric current and convert ... can pick up and detect a wide range of components from ...

Their devices, featuring vertical nanowires only a few nanometers wide ... while tunneling transistors can enable sharp switching slopes, they typically operate with low current, which hampers ...

Since the SSR also needs to have a wide control voltage range, he describes how the two transistor constant-current input block works to limit opto-triac LED current over a range of 2 V to 30 V.
