Inverting Op-Amp Resistors
Estimate resistor ratios for an inverting amplifier's target gain.
Input parameters
Results
Verify supply rails, input range, bandwidth, and loading.
Model & assumptions
Rf = |gain| Rin; Vout = −|gain| Vin; noise gain = 1 + |gain|.
Ideal resistor sizing, not a check of rail or output swing. Confirm input bias, common-mode range and amplifier stability.
