Hi Tosei,
Yes, capacitors could do it quite fast too. However, there are 2 problems with these:
1. Parasitic sensitivity will mean that the parallel and anti-parallel case are not the same, unless of course one uses 2 elements in parallel to realize each unit cap, with top and bottom plates oriented differently for each unit cap. However, there is still parasitic sensitivity which will change the gain from 1 to something less.
2. Loading of the output by the next stage will cause a further error. If the load is a cap, then it translates to another gain error. If it is a resistive load, then the situation is worse. One has distortion.
Regards Vivek
