| description | A complementary metal-oxide semiconductor output driver provides a differential output signal having a particular differential voltage swing and a particular common mode voltage to a differential output node for various types of load circuits coupled to the differential output node. The load circuit may have any impedance within a particular impedance range. A current source provides a current with a variable current component that adjusts the differential voltage swing of the differential output signal. A common mode feedback circuit adjusts the common mode voltage of the differential output signal by sourcing current to the differential output node or sinking current from the differential output node. At least a portion of a current flowing into a load circuit coupled to the differential node is provided by the current source, thereby reusing current from the current source. |
