Abstract: Methods for producing a remote current for driving a load, include one of sourcing and sinking a local current, Iref, through a distributed impedance line, at a first node thereof; the other of sourcing and sinking a remote current, Iref, through the distributed impedance line in response to the local current Iref; determining a rate change of voltage of the first node; and sourcing or sinking additional current, into or out of the first node, in response to the rate of change of voltage of the first node in order to settle the voltage on the distributed impedance line, and apparatus for providing such are disclosed.

Abstract: Methods and apparatus provide for producing a remote current for driving a load, comprising: producing a local current, Iref; amplifying the local current Iref by a value of K to produce a local current K Iref; mirroring the local current K Iref to another location; producing a remote current K Iref in response to the mirroring of the local current K Iref; and dividing the remote current K Iref by a matched value of K to produce a remote current Iref for driving the load.
