Op amp gain nonlinearity
WebAre Op Amps Really Linear? By Barrie Gilbert, ADI Fellow; Manager, NW Labs, Beaverton, OR Everyone knows that op amps are the most linear building blocks in the analog repertoire. If you want nonlinear behavior, you had better look to multipliers or other arcania. But we recognize that every real amplifier has a bit of nonlinearity, http://www.seas.ucla.edu/brweb/papers/Conferences/A&RCICC06.pdf

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. Input Protection WebDue to the high op-amp gain, this circuit tends to oscillate. The capacitor C1 provides a phase-lead component that dampens the oscillations but also reduces the bandwidth of the frequency response. Additional measures can be taken, for example, bias the transistors to allow a small quiescent current, that reduce the region with a horizontal slope in Fig. 9.7 B.
WebDescripción de INA148. The INA148 is a precision, low-power, unity-gain difference amplifier with a high common-mode input voltage range. It consists of a monolithic precision bipolar op amp with a thin-film resistor network. The on-chip resistors are laser trimmed for an accurate 1V/V differential gain and high common-mode rejection.
