Current mirror

Published 15.07.2010 Presenter Anton Pankratov

From biasing using a matched pair of transistors you can easily switch to the so-called current-mirror. The work of the current mirror is "programmed" by setting the collector current of transistor T1. The voltage Ube (base-emitter) applied to the transistor T1 is set in accordance with the given current, ambient temperature and the type of transistor ...
