Answer 1

Part 1: Designing the CircuitTo design a simple amplifier circuit, you will need the following components:1. Transistor (e.g., 2N2222)2. Resistor (e.g., 10kΩ)3. Capacitor (e.g., 1µF)4. Diode (e.g., 1N4148)5. Power supply (e.g., 9V battery)6. Breadboard7. Jumper wiresHere is a step-by-step guide to designing the circuit:Step 1: Draw the Circuit Diagram- Draw the transistor with the collector connected to the base and the emitter connected to the negative terminal of the power supply.- Connect the base of the transistor to the anode of the diode.- Connect the cathode of the diode to the base of the transistor.- Connect the collector of the transistor to the positive terminal of the power supply.- Add a resistor between the base of the transistor and the positive terminal of the power supply.- Add a capacitor between the base of the transistor and the negative terminal of the power supply.Step 2: Build the Circuit on Breadboard- 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.- Connect the base of the transistor to the anode of the diode using jumper wires.- Connect the cathode of the diode to the base of the transistor using jumper wires.- Connect the collector of the transistor to the positive terminal of the power supply using jumper wires.- Connect the base of the transistor to the positive terminal of the power supply using jumper wires.- Connect the base of the transistor to the negative terminal of the power supply using jumper wires.- Connect the positive terminal of the power supply to the positive terminal of the resistor using jumper wires.- Connect the negative terminal of the power supply to the negative terminal of the capacitor using jumper wires.Part 2: Justifying the DesignTo prove that the theoretical calculations match with experimental results, you will need to perform the following steps:Step 1: Calculate the Gain of the Amplifier- 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.- In this case, assume β = 100, Rc = 10kΩ, and Re = 1kΩ.- Calculate the gain: Gain = 1 + 100 * (10k / 1k) = 1001.Step 2: Measure the Output Voltage of the Amplifier- Connect an oscilloscope to the output of the amplifier (collector of the transistor).- Apply a small AC input signal to the base of the transistor.- Measure the output voltage of the amplifier.Step 3: Compare the Calculated Gain with the Measured Output Voltage- If the measured output voltage is 1001 times the input voltage, then the theoretical calculations match with the experimental results.Note: This is a simplified explanation of designing and testing a simple amplifier circuit.
