ABSTRACT:
An input buffer includes a first stage for receiving an input signal and having a first pair of complementary output signals, the first stage including an input circuit for receiving the input signal, an output circuit for generating the first pair of complementary output signals based on the input signal, a resistance feedback circuit connected to the first pair of complementary output signals and generating a feedback signal, and a common mode circuit for balancing the complementary outputs based on the feedback signal.
