ABSTRACT:
In one embodiment, the present invention includes an input buffer with a common gate amplifier having input terminals coupled to receive an incoming common mode voltage. The common gate amplifier may be configured to receive the incoming common mode voltage over a wide range of levels extending from a low end lower than a supply voltage of the input buffer to a high end exceeding the supply voltage.
