You are to research for different methods of biasing BJT circuits, and to choose and describe one of these methods in details in order to design a single stage common emitter or common base amplifier circuit. The report should have the following sections and cover the points listed below: 1. An overview about the purpose of biasing, and different methods of biasing. 2. Design method of your own simple amplifier circuit. 3. Calculations and analysis (including all DC and ac analysis: operating point, current and voltage gains, input and output resistances, voltage waveforms at all nodes in the amplifier circuit..., etc). 4. Simulation results. (Use BC107 for the BJT in your simulation). 5. A comparison between calculated and simulated results, and a conclusion.

Question
Assignment Goal:
You are to research for different methods of biasing BJT circuits, and to choose and describe one of these
methods in details in order to design a single stage common emitter or common base amplifier circuit.
The report should have the following sections and cover the points listed below:
1. An overview about the purpose of biasing, and different methods of biasing.
2. Design method of your own simple amplifier circuit.
3. Calculations and analysis (including all DC and ac analysis: operating point, current and voltage
gains, input and output resistances, voltage waveforms at all nodes in the amplifier circuit..., etc).
4. Simulation results. (Use BC107 for the BJT in your simulation).
5. A comparison between calculated and simulated results, and a conclusion.
Support your design and results with explanation and parametric studies in details. For example, in your
designed circuit, vary the value of the collector resistance Rc to change the mode of operation of the
transistor. Also, design your amplifier circuit according to specific values of the voltage gain and the input
resistance you may choose before designing it. It is also required to take the design steps for the BJT
amplifier circuits into consideration, and the optimum Q-point in order to get the maximum undistorted
output voltage swing (before clipping occurs).
Examples of some biasing methods that are often used:
a) Voltage divider configuration.
b) Base-collector feedback configuration.
c) Using a current source or current mirror.
You may search for other methods.
