Non-Inverting Op-Amp

Ideal non-inverting amplifier model with negative feedback. Assumes linear operation, negligible input current, and a stable closed-loop gain.

Formula

Av = 1 + (R2 / R1), Av(dB) = 20 log10(|Av|).

Typical non-inverting amplifier circuit with R1 as ground resistor and R2 as feedback resistor
Calculate gain for non-inverting amplifier configurations.

All values are unit-aware and validated before computation.
