Abstract
A current source delivering a constant current despite sudden voltage fluctuations which may be applied on its output. This current source includes two branches in parallel, a generating branch and a reference branch. The output current is kept constant by keeping the potential difference across the terminals of the resistors in the generating branch constant, by using a differential amplifier. All the transistors are of the NPN type.
