a) Design a single stage common emitter amplifier using a 2N5089 npn transistor. You should adopt a 4 resistor style configuration. The amplifier is required to provide linear amplification. The specification for your amplifier is to be taken from the table below using your allocated student number. The amplifier is to have a 3dB bandwidth of 100 Hz to 40 kHz. The amplifier is required to drive a 600 ohm load. Vcc(V) Gain Input impedance Output impedance (2) (92) 10 8 600 1000 b) In order to achieve a greater gain modify your circuit with the addition of a capacitor connected across the emitter resistor. Calculate the expected new gain, and verify your result with simulation. Provide an analysis of any changes with regard to the amplifier performance. 1 c) Design and simulate a simple single stage class B power amplifier using suitable (npn) and (pnp) power transistors. The amplifier should be capable of driving the specified power into the specified load. You will need to identify suitable transistors from those available in the LTspice simulator.
