when working with standard op amp circuits im fine with finding worst case offsets, but when working with integrators i get stuck.
how exactly do you find worst case with the capacitor at work? the current across it always ruins my equations
can someone provide an example (any numbers will do, or even just formulae ) on finding worst case with integrators?
lets say, you were given the values of R, C, and all input bias current, offset current, and offset voltage figures.
after grounding the input, and attaching imperfections, my equations (that work fine with standard amplifiers) usually end up extremely messy (due to the capacitor) and finding any worstcase numbers gets incredibly tedious and also look wrong. whats the correct procedure on this?
ive considered removing the capacitor (as it IS dc after all) but then my answers get .. really small.
