Power supply filtering

Hello,

I'm designing a instrumential amplifer circuit (with 3 operational amplifer) that will be used as front-end input buffer for an CCD output signal. For the VCC power supply filtering, I'm thinking about spending each operational amplifier VCC input an seperate Ferrite bead (one option). For an other option, it would be possible to spend one Ferrite bead for all three operational amplifers togehter. However, I do not know what the best (or more feasible) solution is.The intention to use Ferrite Beads is to provide decoupling to the following circuit stages.

 

May somebody can give some recommendation to me.

 

Thanks in advance!
