Abstract

A detailed qualitative discussion is given of the shape of an actual characteristic obtained in the input terminals of a BJT operated in avalanche mode. This characteristic is CCNR (Current Controlled Negative Resistance). Non-linear effects such as those which exist in the internal resistances R_b:R_e:R_c, in the current gain factor α and in the multiplication factor M are taken into account. The discussion is based on the physical model and it shows that the actual (practical) shape of the input characteristic is formed as a result of a 'competition' between two current components which arrive at the base terminal.
