Abstract
There is provided an apparatus for output buffering having a half-swing rail-to-rail structure. The apparatus provides output buffering by using a switch structure in order to attain a high slew rate and low power characteristics, thereby reducing current consumption. The provided apparatus for output buffering having a half-swing rail-to-rail structure includes a first output buffer, driven between a first voltage rail and a second voltage rail and outputting a first output signal in response to a first input signal and a second input signal, and a second output buffer, driven between the first and the second voltage rails and a third voltage rail and outputting a second output signal in response to a third input signal and a fourth input signal.
