Answer / senthil nath

I believe the question is how size NMOS/PMOS to increase the
threshold voltage of inverter? The Vt of a transistor cannot
be altered by changing it's Width or length as per my
understanding. Correct me if I am wrong.

So for the inverter, increasing PMOS width increases Vt of
inverter and increasing NMOS width decreases Vt of inverter.

Answer / senthil nath

@Abhishek,
Vt of inverter means the switching voltage of the inverter
(i.e. the voltage at which the inverter starts to switch)

Answer / abhishek

@ snethil... Vt of the PMOS and NMOSs change in short
channel devices with length... and what is Vt of inverter ?

Answer / ramana

NMOS:Incresing the length vt will decrease.Incresing the
width vt will increase.
PMOS:Incresing the width vt will decrease.Incresing the
length vt will increase.
