Abstract

A low voltage differential swing (LVDS) signal driver having a constant output differential voltage (Vod) over variations in circuit fabrication processes, power supply voltages and operating temperatures (PVT). The minimum and maximum values of the LVDS output signal are monitored and, based upon the difference between them, a signal is provided to the circuit to control the LVDS output signal such that its peak-to-peak value is maintained at a determined value.
