Why reverse connected MOSFET start to turn on at Vgs<Vth?
The circuit shown below is implemented using two AO3400 N-MOSFETs.
AO4300 datasheet here.
The right-hand MOSFET is connected with normal polarity (Vds is positive),
while the left-hand MOSFET is ...

MOSFET switching on
I have a doubt. Consider an N-MOSFET: which is the voltage that can switch on it? The voltage between Gate and? Sometimes I read "between Gate and Bulk", sometimes "between Gate and Source", sometimes ...

When does Direct Source-Drain tunneling become a problem?
Because of the probabilistic nature of quantum mechanics, direct source-drain tunneling is bound to happen as a result of CMOS scaling. The smaller the transistors become, the more tunneling occurs.
