Abstract
A reference current generator configured to produce matched and isolated current references is disclosed. The reference current generator includes a primary reference generator operative to produce a first reference current. The reference current generator further includes a duplicate reference generator operative to produce a second reference current. An adjustment circuit coupled to the primary reference generator and the duplicate reference generator is configured such that the first reference current is substantially matched to and isolated from the second reference current.
