Abstract:
A differential receiver for receiving differential signals including a positive signal and a negative signal and generating an output signal is provided. The differential receiver includes a first comparator configured to compare the positive signal and the negative signal and generate a first signal that is asserted when a difference between the positive signal and the negative signal is larger than a positive offset voltage; a second comparator configured to compare the positive signal and the negative signal and generate a second signal that is asserted when the difference between the positive signal and the negative signal is smaller than a negative offset voltage; a logic gate configured to generate a third signal that is asserted when the first signal and the second signal are negated; and an output circuit configured to generate the output signal based on the first to third signals.
