ON AUTOMATIC ADJUSTMENT OF All BJTs OF A CURRENT MIRROR IN CONSTANT CURRENT REGION

Kimmi Verma, Rishikeya Mishra

The impact of tiny chip has been far-reaching. Many of the electronic products of today, could not have been developed without it. Platform for these chips has been provided by Integrated Circuits (ICs). Since 40 decades ICs have been far revolutionized. Various advancement have been made in these ICs; but still there are some conditions imposed by the designers for proper working of IC. One of such condition exist in biasing of IC. While designing the IC from Bipolar Junction Transistor (BJT), designers introduce that the collector voltage of output BJT used in biased circuit should be greater than a defined minimum value. It implies that user should check every time that whether the circuit is following the specified condition or not. The proposed biasing circuit design in this paper has no such condition and the user will get much freedom.
