Abstract
We describe an input buffer having a stabilized operating point and an associated method. An input buffer may include a first differential amplifying unit to generate a first output signal having a first operating point and a second differential amplifying unit to generate a second output signal having a second operating point. An output control circuit varies respective weights of the first and second output signals responsive to an output control signal. The first differential amplifying unit may operate responsive to a reference voltage and an input voltage signal. The second differential amplifying unit may operate responsive to the reference voltage and the input voltage signal. The first operating point may be relatively higher than the second operating point.
