The inverting input of the ideal integrator in the negative unit step input under voltage, output voltage should rise linearly with time, but the actual integrator of chaos. Increase is not linear, but non-linear rise, which is called the nonlinearity error, the causes are as follows.
(1) integrated operational amplifier open-loop voltage gain and
57 datasheet and input resistance is not infinite.
(2) integrated op amp offset voltage, offset and
57 price and drift is not equal to zero power.
(3) the integration capacitor leakage, and
57 suppliers and there is dielectric loss and absorption effects.
