Answer Posted / chandrasen mourya
This is related to the iron losses & copper losses of the
Trafo. Iron losses are constant ie from No load to full
load. Copper losses varies depending on the load 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.
