Abstract
The methods and systems presented herein provide an improved means of correcting the variation of Voltage Output Differential (VOD) in differential drivers. In some embodiments, a high-precision reference voltage is generated not only based on a desired VOD, but also by monitoring the Voltage Common Mode (VCM) in a differential driver. In some embodiments, the VOD is then compared with the high-precision reference voltage to correct the output current. The result is a low-variation output voltage.
