Claim Text:
1. A method of regulating an output voltage amplitude of a low voltage differential signaling (LVDS) driver, the method comprising: receiving a differential output signal from a switched-polarity current generator of an LVDS driver at an output voltage amplitude regulator of an LVDS driver; detecting an output voltage amplitude of the differential output signal; detecting a common mode voltage of the differential output signal; subtracting the common mode voltage from the output voltage amplitude; comparing the output voltage amplitude to a reference voltage at the output voltage amplitude regulator after the subtracting the common mode voltage from the output voltage amplitude; 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.
