THEORY :-

1.      INVERTING :-

●       An opamp is a high-gain differential amplifier with very high input impedance. Very high open-loop gain allow for creating amplifiers with stable gain using feedback.

●       In an inverting amplifier, the input signal is applied to inverting pin of the opamp and there is a phase inversion (180 degree phase difference between output and input)..

●       The amplification factor or gain can be controlled by external components - Resistor in feedback path Rf and input path Ri.

●       Voltage gain of the non-inverting amplifier is given by:

                                               Gain = -R_f/R_i

●       While designing opamp circuits, one has to be careful about output saturation - if the gain or input signal is high enough to drive output beyond the supply voltages (Vcc and Vee), the amplifier goes into saturation and output is limited to supply voltages.

2.      NON – INVERTING :-

●       An opamp is a high-gain differential amplifier with very high input impedance. Very high open-loop gain allow for creating amplifiers with stable gain using feedback.

●       In a non-inverting amplifier, the input signal is applied to noninverting pin of the opamp and there is no phase inversion between output and input.

●       The amplification factor or gain can be controlled by external components - Resistor in feedback path Rf and input path Ri.

●       Voltage gain of the non-inverting amplifier is given by:

                                             Gain = 1+ (R_f / R_i)

●       While designing opamp circuits, one has to be careful about output saturation - if the gain or input signal is high enough to drive output beyond the supply voltages (Vcc and Vee ), the amplifier goes into saturation and output is limited to supply voltages.
