Theoretic curves of drift transistor current gain

Intrinsic common-base, short-circuit current gain analysis of drift transistors may be aided by means of a simplified approximation equation. The accuracy of the equation may be controlled by the investigator. A graphic solution for determining this parameter of moderate drift field transistors may be obtained by using the arcs of circles. The interrelation between the graphic analysis and the theoretic approximation provides a flexible yet accurate method of analyzing this parameter.
