Common-Base Amplifier D. Surti and A. Parikh 5. Conclusions and Remarks C1) Table C1(a): Calculated and measured voltages of the CE amplifier. V C [V] V E [V] V E2 [V] Calculated values 12.02 7.53 - Measured values 12.1 7.78 - Percent error, % 0.702% 3.32% - Table C1(b): Calculated and measured voltages of the two-stages amplifier. V C [V] V E [V] V E2 [V] Calculated values 12.02 7.53 11.32 Measured values 11.99 7.783 11.146 Percent error, e% 0.25% 3.25% 1.56% The percentage errors attainted are relatively small and show that the manual calculations were near the measured values. Some contributions to these errors are, noise, static interference, and slightly loose connections.
