Description:

A microphone has a peak open circuit voltage of 1mV with an output resistance of 10kΩ.

Design an amplifier to allow this microphone to drive a 15Ω speaker in such a way that

the magnitude of the gain – bandwidth product is maximised. The gain bandwidth

product is determined as

v ( H L ) G − BW =| A | f − f

The following constraints are placed on your design.

Skills required: winspice

1. The circuit is to be biased from a +12 / -12V DC power supply.

2. The circuit should produce no clipping or distortion in the output voltage

waveform when the input voltage is at its maximum value (1mVpk).

3. You can only use three transistors (and should use all three transistors). You have

one each of the following: NPN transistor 2N3904, PNP transistor 2N3906 and a

p-channel JFET 2N5460.

As part of the design process you should simulate your circuit and confirm its operation.

1. A complete circuit diagram for your circuit.

2. Manual bias calculations showing all terminal voltages and collector (drain)

current for each transistor.

3. Manual gain calculations. This should be presented as small signal input

resistance, output resistance and gain calculations for the individual stages and

then a total gain calculation (that includes source and load resistances)

4. Manual bandwidth calculations. If there is a single stage that clearly determines

the high frequency cut-off of the circuit then you need only include calculations

for it and not all transistors.

5. A simulation output that shows the input and output voltages waveforms

demonstrating that the output waveform remains undistorted for the maximum

input voltage.

6. A simulation output showing the frequency response of the output waveform.

7.A copy of your simulation file (source file only) submitted (preferably) electronically
