I have been reading the following tech note from Analog Devices that discusses designing an op amp circuit to compensate for the input bias current: https://www.analog.com/media/en/training-seminars/tutorials/MT-038.pdf
I would like to understand how to better calculate the value of a compensation resistor in an integrator op amp design:
As I understand it, input bias currents are what can lead to op amp saturation when nothing is connected to the input of an integrator. Is this correct? Is an input bias compensation resistor necessary in an integrator?
