Experiment: Multi-Transistor Amps.

1.

Set up the CE-EF amp shown in Fig. 4.2. Let $R_1=100K,~R_2=10K,~R_C=10K,~R_{E1},~R_{E2}=1K,~R_{L}=10K,~C_1=C_2=C_E=0.1\mu F$.

2.

Calculate the midband gain of the circuit.

3.

Measure the frequency-dependent gain for each decade ranging from 10Hz to 10MHz.

4.

Use the OCTCA to estimate the frequency response of the circuit.

5.

Draw a Bode plot of your result of gain versus frequency for the measured and theoretical values.
