Provided is an input buffer whose input capacitance presented to input signals can be reduced. The input buffer includes a first differential amplifier which compares the sizes of a first input signal and a second input signal and outputs an output signal as the result of the comparison; a second differential...http://www.google.de/patents/US20050068067?utm_source=gb-gplus-sharePatent US20050068067 - Input buffer capable of reducing input capacitance seen by input signal
