Shielding Diagram Of A Non Inverting Amplifier. Although the inverting amplifier is preferred in many cases it has two drawbacks. Notice that the input is applied to the non inverting input while the feedback is applied to the inverting input.

The circuit diagram of an ideal non inverting amplifier is as shown in the figure below. The following circuit diagram shows the non inverting amplifier using op amp. From the circuit it can be seen that the output voltage is potentially divided across resistors r1 r1 in the above picture and r2 rf in the above picture before it is applied to the inverting input.

In this amplifier the input signal and output signal are in phase i e.

Voltage follower unity gain buffer if we made the feedback resistor rƒ equal to zero rƒ 0 and resistor r2 equal to infinity r2 then the resulting circuit would have a fixed gain of 1 unity as all the output voltage is fed back to the inverting input terminal negative feedback this configuration would produce a special type of the non inverting amplifier circuit. The schematic diagram for a non inverting amplifier shown in figure b output of this circuit is in phase with the input. The non inverting amplifier configuration is one of the most popular and widely used forms of operational amplifier circuit and it is used in many electronic devices. In this amplifier the input signal and output signal are in phase i e.
