Hello all,
Is it better to have only 1 centralized bandgap reference circuit and use current mirror to bias other circuits on the chip? Or is it better to have separate reference for separate circuits on the chip?
There are some arguments regarding trade-off between reliability and power. Some argue that by using multiple bandgap, I will get better reliability becuase in case one of the bandgap fail, only one part of the IC will fail.
But how often do these bandgap references fail? Anyone encounter any problem with a bandgap reference before?
Thanks and Regards, chase.
