Operational Amplifier Application
Part A: The Inverting amplifier circuit
3-
4- Calculate the voltage gain Av.
Av =

𝑹𝟏
=
−(𝟐.𝟐 𝒌𝛀)
(𝟏.𝟎 𝒌𝛀)
= -2.2
5- What is the phase shift between the input and the output signals?
Phase Shift = 180 ⁰ degrees, the Output Gain of this Amplifier is Negative since the Input Signal
(Vin) is linked to the Inverting input (-).
6- Increase the function generator amplitude until the output signal start to clip, read
the value of the input voltage that saturate the op-amp and find the maximum
value of the output voltage.
When the Amplitude increase, this will result in a clip by 2 Volts approximately
(2 Vp-p to 4 Vp-p). The Clipping also occurs when the Feedback Resistance increases .

Part B: The Non - Inverting amplifier circuit

(𝟏.𝟎 𝒌𝛀)
5- What is the phase shift between the input and the output signals?
Phase Shift = 0 ⁰ degrees, as the application of the Input Voltage Signal (Vin) to the non-inverting
input results in a Positive Output Gain for the amplifier.
Part C: The Voltage Follower circuit
4- Increase the input voltage amplitude to 3 Vp-p, 4 Vp-p and measure the output
voltage. Comment on your readings.
The output signal and the input signal are Similar, No Effect by increasing the Voltage
Amplitude.

5- Calculate the voltage gain Av.
The Output Signal is identical to the Input Signal if the non-inverting Amplifier circuit's
feedback resistor (RF) is replaced with a short circuit (RF = 0). Hence the gain Av = 1
6- What is the phase shift between the input and the output signals?
Phase Shift = 0 ⁰ degrees, as the output signal is identical to the input signal.
Part D: The Comparator circuit
Vref=0 V
Vref=2 V
5- Does the output signal differ when Vref = 0 V from that
when Vref = 2 V? Explain.
The Output will saturate at the highest possible negative voltage when the inverting input (Vin) is
greater than the inverting input (Vref). The maximum negative voltage in the situation of
(Vref = 2V) is -5.003 V and the most positive voltage is 3.003 V.
