摘要：
An low voltage differential signaling (LVDS) driver is provide having an output voltage amplitude regulator for regulating an output voltage amplitude of the LVDS driver by receiving a differential output signal from a switched-polarity current generator of the LVDS driver at an output voltage amplitude regulator of the LVDS driver, detecting an output voltage amplitude of the differential output signal, comparing the output voltage amplitude to a reference voltage at the output voltage amplitude regulator and regulating a steering current of the LVDS driver based upon the comparison between the output voltage amplitude and the reference voltage to regulate an amplitude of the differential output signal at one or more loads of the LVDS driver.
