Unformatted text preview: tion. e) To increase the ratio of the electron current injected into the base and the hole current injected into the emitter. ECE ­606 2 Spring 2013 Exam 4: ECE 606 2) Consider an NPN BJT with the following parameters: I Ep = 0.01 mA I En = 2 mA I Cn = 1.98 mA Spring 2013 I Cp = 0.0001 mA 2a) Determine the base transport factor, ! T . Solution: I 1.98 ! T = 0.99 ! T = Cn = = 0.99 I En 2.00 2b) Determine the emitter injection efficiency, ! Solution: I En 2.00 ! = 0.995 != = = 0.995 I En + I Ep 2.00 + 0.01 2c) Determine the curre...
