Abstract
A current mirror,includes a current mirroring transistor,having a selected aspect ratio for conducting a mirrored current of a selected mirroring ratio with respect to a reference current. A plurality of reference current transistors,are disposed in parallel with current mirroring transistor,, each of the reference current transistors,having a current path coupled to a source,of the reference current and a selected aspect ratio. A switch,is coupled to a control terminal of a selected reference current transistor,, for selectively turning on and turning off a selected reference current transistor,to adjust the mirroring ratio.
