Transcribed Image Text:

You are given a 2n2222A transistor. It has a ẞ of 255 and an Early Voltage of -74V. (From the datasheet). A) Design a circuit to give you an overall voltage gain magnitude of 200 with an input resistance of at least 5KQ. Your load resistance is 220KQ. You have a +12V supply and a -12V supply (you don't have to use both). Your supply of parts includes any capacitor or resistor value that you need. B) Simulate your circuit with a 5mV input signal (you may use any frequency signal you choose). C) (Optional) For a small bonus, use simulation to demonstrate what kind of filter this circuit is (low pass, high pass, band pass).
