What I mean about "Reverse polarized circuit" is that it can take the input voltage and reverse it taking the 0 as axis of symmetry.

I want to realize it using analog circuitry like MOSFETs or OP Amp. it has to be working from -1.8V to 1.8V range at least.

Anyone has idea about this?

I'd guess that you're looking for an op amp hooked up in
unity gain inverting configuration, and either rail-rail I/O
or excess supply headroom.

I might direct you to any of the older National databooks'
application circuits that follow their data tables. Or any of
many op amp applications books.
