I'm confused about Input Bias Current, is it "side effect" characteristic, where the current "leak" from the op amp. or it's a must to operate the op amp? for example if I have in the datasheet a 1pA input bias current, I should provide a 1pA to the inputs of op amp.
Note: if the type of op amp make a difference, I'm interested in
LTC6078/LTC6079
Thanks
