What is Summing Amplifier (Adder) Using Op-Amp? Circuit Diagram, Working, Derivation & Formula

It is possible to apply more than one input signal to an inverting amplifier. This circuit will then add all these input signals to produce their addition at the output. Such a circuit will then be called as an adder or a summing amplifier.

What is Voltage Follower (Buffer) Using Op-Amp? Circuit Diagram, Working, Derivation & Formula

The voltage gain of the Voltage Follower (Buffer) circuit is 1 i.e. the output voltage will be equal to and in phase with the input voltage. In other words, the output voltage follows the input voltage. Hence the name voltage follower. Thus voltage follower is a non-inverting amplifier with a voltage gain of unity. Figure

What is Inverting Amplifier Using Op-Amp? Circuit Diagram, Working, Derivation & Formula

In Inverting Amplifier, the amplified output signal will be 180º out of phase with the input signal. In other words the output signal is “inverted” as shown in Fig. 2. Therefore this amplifier is known as the inverting amplifier. Figure 1: Inverting Amplifier.
