Abstract: A semiconductor device includes a pair of transistors configured to implement buffering of input data to outputs. The semiconductor device also includes a first transistor configured to receive a common-mode of the outputs at a gate terminal of the first transistor. The semiconductor device also includes a current source configured to control a tail current from the pair of transistors. Additionally, the semiconductor device includes a second transistor configured to adjust the tail current based at least in part on changes in a reference voltage used by the pair of transistors to buffer the input data. Furthermore, the semiconductor device includes a third transistor configured to adjust the tail current based at least in part on changes in locally generated reference voltage based at least in part on a process and temperature variations.
