Areky_qin said:BTY, we have designed a bandgap with a op, the simulation result is very good, just as the power supply range, temperature characteristic, but when we test the chip,the bandgap block not work, so i think there r more things to think about, not only some paper can show all the information, tape-out and test results show all.
Yes, I agree that there are more things need to be considered in real situations. So, for your case, what is the probem of the bandgap block? Do you find out the reasons finally?
