why we use lamination or layer by layer cor used?

Answer Posted / gautham sharma

We use laminated metalic plates to make the cores of transformers and electric motos and many other things. This is to avoid energy loss in the form of Eddy Current. Eddy current are circular loops of current which form conductind plates or surfaces which can result energy loss in the form of heat. Laminated cores increase the resistance by a substantial amount and reduces eddy current.

Is there a possibility to use such a treshold voltage for the NMOS part of a CMOS circuit that during the switching it will start conducting only after the PMOS part will be already closed, by this eliminating the leakedge current? Please note, I'm not asking about the well bias in standby mode, but about the "antileakedge" measures during normal operation.
