Systems are provided for generating and distributing a plurality of
reference currents on an integrated circuit. More particularly, an
integrated circuit is provided which includes a reference current
generating system. The reference current generating system includes a
first reference current generator disposed at a first location of the
integrated circuit which is operable to generate a plurality of first
reference currents. A plurality of second reference current generators
are disposed at a plurality of second locations of the integrated
circuit. Each of the second reference current generators are operable to
generate a second reference current from one of the plurality of first
reference currents. In a particular example, the first location at which
the first reference current generator is disposed is a central location
and the second locations are disposed remote from the first location.
