Working Principle
A non-inverting amplifier produces an output signal in phase with its
input signal. Similar to an inverting amplifier, the basic structure of a non-
inverting amplifier consists of an op-amp configured in negative feedback
and two resistors. However, the voltage gain of a non-inverting amplifier
is greater or equal to 1, and the input signal is connected to the non-
inverting input, which can be treated as an infinitely high impedance
input.
