Abstract
Some embodiments of the invention include an input buffer having multiple differential amplifiers for receiving input signals to generate an output signal. The input buffer operates in a relatively low supply voltage and a relatively wide range of signal levels of the input signals while improving the symmetry between rising and falling signal transitions of the output signal. Other embodiments are described and claimed.
