Abstract

Bipolar junction transistors (BJTs) have been at the core of linear electronics from its beginnings. Here, we suggest an Early-based inspired geometric model of BJT devices and its application to derive models of related electronic circuits (more specifically a common-emitter configuration). The approach involves using a beam of isolines converging at the Early voltage as the model of a BJT. The angles of the isolines are experimentally verified often to vary almost linearly with the base current. A numerical methodology is suggested for the Early voltage estimation and applied to 12 real-world small signal NPN BJTs. Interesting results are obtained, including the identification of diverse Early voltage values for different BJT types and estimation of transfer functions. (AU)
