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 ...
It has long been known that the simple combination of a depletion-mode MOSFET (and before these were available, a JFET) and a resistor made a simple, serviceable current source such as that seen on ...
Several Design Ideas (DIs) have employed the subject ICs to implement programmable current sources in an innovative manner [Editor’s note: DIs referenced in “Related Content” below]. Figure 1 shows ...
