Consider an NPN BJT with the following parameters. Beta = 85, Cmu = 1 pF, Co = .5 pF, and Cpi = 6 pF. With IC = 70 mA, r0 = 50 Ohms. RLOAD = 50 Ohms and RSIG = 1K. The available power supply is +12V DC. All coupling caps are 1 uF. Design an amplifier circuit using this transistor with a gain of -50. Calculate the upper and lower 3 dB points of your design. There is a 10% bonus for showing that your circuits works properly in simulation.

Expert Solution

Lower 3dB frequency = 53 KHz, Upper 3dB frquency = 100 MHz

Consider a Si NPN BJT. Discuss how an change in one of the design parameters affect the emitter injection efficiency, the base transport factor, the common emmiter current gain, and the early voltage. Assume complete ionization. Further assume the carrier mobility and the minority carrier lifetime are independent of the change in design parameters. (a) Increase emitter doping (b) Increase base doping (c) Increase base width (d) Increase collector doping
