Abstract
A method and device for controlling the common-node output voltage of a differential buffer is disclosed. According to the invention, the common-mode output voltage of the differential buffer is controlled to a desired value by supplying a first current to the output of the differential buffer and supplying a second current to the output of the differential buffer, the second current being opposite in polarity and lower in magnitude than the first current. The common-mode output voltage of the differential buffer is sensed and an adjustment current is added to the second current to adjust the common-mode output voltage to the desired value.
