WebNon-inverting Operational Amplifier Voltage Follower. In this non-inverting circuit configuration, the input impedance Rin has increased to infinity and the feedback impedance Rƒ reduced to zero. The output is connected directly back to the negative inverting input so the feedback is 100% and Vin is exactly equal to Vout giving it a fixed gain ...

WebGain nonlinearity cannot be trimmed; it is a function of careful design and die layout. The use of common centroid geometries and iso-thermal layout cancels the errors due to die stress and thermal gradients. If this is not done correctly, all the trimming in the world will not improve performance.
