Inverting Op-Amp

Ideal inverting amplifier model with negative feedback. Assumes linear operation, negligible input current, and a virtual ground at the inverting input.

Formula

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

Typical inverting amplifier circuit with R1 as input resistor and R2 as feedback resistor
Solve inverting amplifier gain and output voltage relationships.

All values are unit-aware and validated before computation.
