bandgap voltage reference?

This Bandgap can generate a Vbg that is less than Vref=1.205V,R1=R3,R2=R0,R1+R2=R3+R0=R,
& w" V/ z8 B2 ]7 F: AR/R4 should be around 11 or 12 as convention bandgap has output Vref=1.205V,than you will get output in this bandgap as Vbg=Vref*R5/R.If you have chance,you can see some papers,there are many paper s about this literature.
