2.1h.3i Noninverting Amplifier

Noninverting Amplifier

A noninverting amplifier is an op-amp configuration that does not invert the source voltage and simply adds a gain to the output voltage, such that $V_o=G{V}_s$, where $G=\frac{R_1+R_2}{R_2}$. The figure below visually describes the configuration.
