0.3uA ?? It is close to the leakage current and also will give a poor noise performance .. isn't it ?

Have you taped out such design or is for academic purpose ? Coz I have serious doubts regarding these current levels. coz when you have say 1:24 ratio of bjts 0.3u/24 is like 12.5nA !! Not far from
leakage currents.

S. the PDF below. This method can also be applied for a current-mode CMOS bandgap reference circuit in order to get along with lower resistance values.kishore2k4 said:Lets say you are using the standard current-mode CMOS bandgap reference topology. For a bias current of 1uA+1uA the value of R1 would be around 50K and R2 would be nearly 10-12 times of that around 500k. Aren't these resistor values quite high with significant impact on area?
No, sorry, this is company confidential. Hope for your comprehension!kishore2k4 said:@erikl: May I please know a bit more about your bandgap circuit.
