| Mar 14, 2014 at 5:55 | comment | added | markrages | @richieqianle, yes, often abbreviated in datasheets to "PSRR" for power-supply rejection ratio. | |
| Mar 14, 2014 at 4:43 | comment | added | richieqianle | @markrages You are right. I am not sure about the worst ripple allowed. The only spec I am aware is that the first stage preAmp turning photodiode current into voltage should have the precision of 1pA. To connect ripple allowed and my spec, is "ripple rejection ratio" the term to study? | |

| Mar 13, 2014 at 17:13 | comment | added | markrages | You need a better spec. ("high precision" isn't a spec.) How much ripple is allowed? What is the ripple rejection of the load circuits, both at DC and at higher frequency? | |
