Pnp transistor with base connected to collector

[QUOTE="DS2016, post: 5495029, member: 596531"] Hello all, I have a problem to understand a pnp transistor with base (B) connected to collector (C). When I set the VE (voltage of emitter) at 0 V and the VB, which is the voltage of base and collector nodes, since they are tied together), decrease from 0 V to -1.0 V,the simulation result shows me that the emitter current (IE) is equal to | IB + IC |. I can understand the result regarding the equivalent circuit of pnp, but i can not understand the physics behind this, because VBC=0 V. Does operate the diode of BE junction in forward-biased? what is about the diode of BC junction, when VBC=0 V? I would be thankful for any reply [/QUOTE]
