DIFFERENTIAL RECEIVER, ELECTRONIC DEVICE AND INDUSTRIAL DEVICE INCLUDING THE SAME, AND METHOD OF RECEIVING DIFFERENTIAL SIGNAL

摘要

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.

1. A differential receiver for receiving differential signals including a positive signal and a negative signal and generating an output signal, comprising:
a first comparator, which has a positive offset voltage, 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 the positive offset voltage; a second comparator, which has a negative offset voltage, 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 the 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.
