Non-Inverting Op-Amp Design
Estimate feedback resistance ratios for positive closed-loop gain.
Input parameters
Results
Check common-mode range, output swing, and stability.
Model & assumptions
Rf = (gain − 1)Rg; Vout = gain Vin. Gain 1 is a voltage follower.
Ideal model. At unity gain use a feedback connection and omit the ground resistor; verify unity-gain stability.
