Problem 3 (25 points) The electron and hole currents inside a certain BJT biased in the active mode are shown in the figure below. All the currents are referenced to 14, the hole current injected into the base. (a) (9 points) What type of BJT (npn or pnp) is this device? On the diagram, indicate with arrows the direction of the electron and hole currents and the corresponding motion of the electrons and holes in the device. (b) (16 points) Determine the base-transport factor (B), the emitter injection efficiency (y), the common-emitter current gain (), and the current transfer ratio (a). electron current hole current 0.9911 11 0.9911 0.011 0.0114 10-511 Emitter Base Collector
