HAL,
1986E.B sending end to receiving end 33kv ug cable laid 8Km,receiving end to ss1,ss2,ss3,ss4 all are Approx 800 Mtr,can go for 33KV to 430V or 33kv to 11kv in receiving end and 11kv to 430 near ss ,which one is good for technically and economically.

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.
