摘要：A low voltage differential swing (LVDS) signal driver having substantially
constant output differential voltage (Vod) and substantially constant output offt
胎动异常voltage (Vos) irrespective of variations in circuit fabrication process, power supply voltages and operating temperatures (PVT), as well as circuit load conditions. A driver replica circuit which replicates a portion of the actual LVDS driver circuit conducts a driver replica operating current that is a scaled replica of the LVDS driver operating current. Operating voltages within the LVDS driver and driver replica circuits are monitored and controlled by bias voltages provided by the driver replica circuit. The desired scaling factor for the operating currents is ensured by appropriate scaling of the sizes of the circuit devices within the LVDS driver and driver replica circuits.
