![]() As long as the input signal stays within the op amp's frequency limits, well above the noise floor, and the output does not saturate, accurate integration results.Ĭircuits of this type can be used to model any number of physical processes. Generally, slew rate performance is not paramount, as integrators tend to “smooth out” signal variations. The limited frequency response and noise characteristics of the op amp will also play a role in the ultimate circuit accuracy. One possible solution is to use an FET input op amp. If the input signal current is relatively low, the idealization that all of the input current will bypass the op amp and flow directly into the capacitor is no longer realistic. One possible source is the op amp's input bias current. Small errors occur due to the approximations made. ![]()
