for silicon, the bandgap votlage is 1.2 volt. how about in those short channel process? the votlage supply is less than 1V, how to generate a 1.2 volt bandgap voltage?
 

bandgap voltage

The bandgap voltage of silicon is 1.12eV. That is Ec-Ev

That does not depend on a mosfet channel length.

Maybe you mean the "magic" voltage that is typically the output of a Brokaw bandgap cell? A current summing bandgap can add PTAT and CTAT currents below 1.2V rather than adding PTAT and CTAT.
