6.39 A particular pnp transistor operating at an emitter current of 0.5 mA at 20°C has an emitter–base voltage of 692 mV. (a) What does v EB become if the junction temperature rises to 50°C? (b) If the transistor is operated at a fixed emitter–base voltage of 700 mV,what emitter current flows at 20°C?At 50°C?
