AS FAR AS I KNOW MOS DIODES ARE USED IN IC.i.e,the nmos or pmos with gate and drain shorted.

Thanks for ur reply... In my intreview i was asked "How a diode is reduced to this much less size ".. Do u Know the answer for it??

They create superdiodes from op amp circuits which are of course very small in size !! Look up the area of precision circuits .. Superdiodes have a very low Vt value ~ 0 and can be used as a rectifier ..
