By using dual bipolar devices in one case, the manufacturer nearly perfectly matches the two devices. Although this Design Idea describes a positive power supply, you can realize a similar ...

But from there he moves on to the juicy bits. He builds a transistor-based constant current driver, then adds voltage regulation for the circuit as seen in the schematic on the left.

The use of constant current sinks/sources (CCS’s) are common in Hi-Fi. They have a variety of purposes especially in tube audio electronics, most of which are employed to force other tubes in the ...

Can the classic discrete one transistor constant (ish) current source do something similar? – see the top diagram, where the same circuit is connected both ways around to an ac voltage source. The 50Ω ...
