Design a common base amplifier using a common NPN BJT (2n2222). Bias the amplifier at a level of 2mA. Use Vcc of 15V. Set the bias such that Vc is 9V quiescent and Ve is 2V quiescent. Use a load equal to 300 ohms and a source impedance equal to 25. Calculate the values of Cin, Cout and Cb, seting the lower 3dB frequency of Cin and Cout at 1k hz. Set the lower 3dB frequency of Cb at 8k hz.

Using the high frequency hybrid pi model, calculate the amplifier input impedance, theoretical gain and upper 3db point. Show all design assumptions, justifications and calculations and compare your design with a circuit simulation.
