  • RE: OPA392: Measuring current noise of a current source?

    Daniel, For first stage OPA375 helps a lot ; for each sequent stage it is less help. Vos is a DC value that create a DC offset that only affects DC performance. Noise is entirely AC. So DC does not matter. C1 and C2 throw away all the source DC. The only…
