Non-inverting Amplifier
This experiment is very similar to the previous one, the inverting amplifier.
Objective
Wire an non-inverting amplifier using an Op-Amp, like µA741 or OP07, and test it.
Procedure
- Make the connections on bread board as shown in the figure.
- Set WG amplitude to 80 mV and frequency to 1000 Hz
- Enable A1 and A2, and set ranges to 1V
- Enable the amplitude and frequency displays of A1 and A2.
- Make connections and calculate the voltage gain from the output
- Change gain by changing the resistor values.
The amplitude gain and and the phase difference can be observed from the output below.
Discussion
Using expEYES, it is not possible to study the high frequency response.
