Part 1: Designing the Circuit<br /><br />To design a simple amplifier circuit, you will need the following components:<br /><br />1. Transistor (e.g., 2N2222)<br />2. Resistor (e.g., 10kΩ)<br />3. Capacitor (e.g., 1µF)<br />4. Diode (e.g., 1N4148)<br />5. Power supply (e.g., 9V battery)<br />6. Breadboard<br />7. Jumper wires<br /><br />Here is a step-by-step guide to designing the circuit:<br /><br />Step 1: Draw the Circuit Diagram<br />- Draw the transistor with the collector connected to the base and the emitter connected to the negative terminal of the power supply.<br />- Connect the base of the transistor to the anode of the diode.<br />- Connect the cathode of the diode to the base of the transistor.<br />- Connect the collector of the transistor to the positive terminal of the power supply.<br />- Add a resistor between the base of the transistor and the positive terminal of the power supply.<br />- Add a capacitor between the base of the transistor and the negative terminal of the power supply.<br /><br />Step 2: Build the Circuit on Breadboard<br />- Place the transistor on the breadboard with the collector connected to the positive terminal of the power supply and the emitter connected to the negative terminal of the power supply.<br />- Connect the base of the transistor to the anode of the diode using jumper wires.<br />- Connect the cathode of the diode to the base of the transistor using jumper wires.<br />- Connect the collector of the transistor to the positive terminal of the power supply using jumper wires.<br />- Connect the base of the transistor to the positive terminal of the power supply using jumper wires.<br />- Connect the base of the transistor to the negative terminal of the power supply using jumper wires.<br />- Connect the positive terminal of the power supply to the positive terminal of the resistor using jumper wires.<br />- Connect the negative terminal of the power supply to the negative terminal of the capacitor using jumper wires.<br /><br />Part 2: Justifying the Design<br /><br />To prove that the theoretical calculations match with experimental results, you will need to perform the following steps:<br /><br />Step 1: Calculate the Gain of the Amplifier<br />- The gain of the amplifier can be calculated using the formula: Gain = 1 + β * (Rc / Re), where β is the current gain of the transistor, Rc is the collector resistance, and Re is the emitter resistance.<br />- In this case, assume β = 100, Rc = 10kΩ, and Re = 1kΩ.<br />- Calculate the gain: Gain = 1 + 100 * (10k / 1k) = 1001.<br /><br />Step 2: Measure the Output Voltage of the Amplifier<br />- Connect an oscilloscope to the output of the amplifier (collector of the transistor).<br />- Apply a small AC input signal to the base of the transistor.<br />- Measure the output voltage of the amplifier.<br /><br />Step 3: Compare the Calculated Gain with the Measured Output Voltage<br />- If the measured output voltage is 1001 times the input voltage, then the theoretical calculations match with the experimental results.<br /><br />Note: This is a simplified explanation of designing and testing a simple amplifier circuit.
