Abstract:
    Apparatus, system, and method including a single common node bias voltage; at least a first current path to drive a bias current based on the single common node bias voltage; at least a first current mirror to mirror the bias current in a second current path; and an output current path comprising current drivers to drive source and sink currents that are matched to the bias current. The first current mirror may include at least one partial cascode current mirror. The apparatus and system provide a single common node bias voltage to generate a bias current; mirror the bias current in at least one current path; and output well-matched output source and sink currents based on the bias current.
