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.
