Differential Amplifier Offset Compensation at Lucy Hutchinson blog

Differential Amplifier Offset Compensation. Input offset voltage is modeled as a voltage source,. A temperature differential of \(0.001^{\circ} c\) results in an offset of \(2 \mu v\) for a differential pair that is perfectly matched when the tem­peratures of the transistors. In practice, a small differential voltage must be applied to the inputs to force the output to zero. Objective of compensation is to achieve stable operation when negative. In high source resistance applications, offset voltage at the amplifier output may be adjusted by adjusting the value of r3 and using the variation in voltage drop across it as an input offset. Looking at the inside of an op amp, we can see that the mismatch of transistors q 1 and q 2 in the differential input pair is what causes the offset. Offset adjust for a differential op amp driving an adc. General principles of op amp compensation. This is known as the input offset voltage, vos.
