Operational Amplifiers Experiment #10 Question 1: For the inverting amplifier calculate the actual voltage gain. Voltage gain is the output divided by the input. Next, calculate the theoretical voltage gain using the measured resistances and the formula from your pre-lab. Calculate the percent error between the actual and theoretical voltage gains. Calculating the actual voltage gain: 5 . 20 410 . 0 4 . 8 = - = Volts Volts V V input output Calculating the theoretical voltage gain, using the equation from the pre-lab: 522 . 19 020 . 1 913 . 19 1 2 - = - = = - k k V V R R input output Calculating the percent error: % 76 . 4 % 100 5 . 20 522 . 19 5 . 20 % 100 = - = - measured computed measured Question 2: For the non-inverting amplifier calculate the actual voltage gain. Next, calculate the theoretical voltage gain using the measured resistances and the formula from your pre-lab. Calculate the percent error between the actual and theoretical voltage gains. What is the difference between the voltage follower and the non-inverter amplifier? Calculate the voltage gain of the voltage follower using the result from pre-lab. Is the measured gain consistent with your calculated one?
