Mech Efficiency = [Volume in(m3/Sec) * Average Differential
Pressure]/[102*power input to fan shaft in KW]

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.
