Question
# Setting Up a Common Emitter Amplifier Circuit ## Circuit Diagram Description The diagram illustrates a common emitter amplifier circuit. The key components include: - **Vin**: AC input voltage source, connected to ground. - **C1**: Capacitor connecting the input voltage to the base resistor \( R_B \). - **\( R_B \)**: Base resistor, connected in series with the input. - **\( V_{cc} \)**: DC power supply connected to the collector resistor \( R_L \). - **\( R_L \)**: Collector resistor, connected to the transistor collector. - **Transistor**: Positioned between \( R_B \) and \( R_E \), with collector, emitter, and base terminals. - **\( V_{ce} \)**: Voltage between collector and emitter. - **\( R_E \)**: Emitter resistor, in series with capacitor \( C2 \). - **C2**: Capacitor connected to the emitter, providing AC ground for signal frequencies. ## Instructions 1. **Objective**: Set up the circuit such that: - Collector current (\( I_C \)) = 2mA - Collector-Emitter Voltage (\( V_{CE} \)) = 6 volts 2. **Component Selection**: - Determine \( R_B \), \( R_E \), and \( V_{CC} \) to meet the above conditions. - Choose capacitors \( C1 \) and \( C2 \) to operate at mid frequencies. 3. **Measurement**: Measure the voltage gain as a function of frequency. ## Given Values - \( C_1 = 10 \, \mu F \) - \( C_2 = 20 \, \mu F \) - \( \beta = 100 \) - \( f_L = 50 \, Hz \) - \( f_{LE} = 450 \, Hz \) These parameters will aid in setting up and analyzing the circuit's performance for educational purposes.
