Answer Posted / somasundaram t
ward leonard method is one of the dc motor speeed
control.this method requires combination of one motor
generator set for controlling the one DC motor.so this
method becomes expensive.and also requires high
maintanence.power consumption ,losses also more.this method
got too failure after the power semiconductor controllers
has been introduced.

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.
