Abstract
A comparator includes: a first selector for selecting one of a first reference voltage and a first correction reference voltage, based on a first determination value of data at a past time of a first adjacent channel; a first comparator for comparing the difference between a voltage selected from the first reference voltage and the first correction reference voltage and a second reference voltage with an input voltage at a current time of a target channel; and a first output unit for determining an output voltage at the current time of the target channel, based on the comparison result of the first comparator.
Claims20
A comparator comprising:
- a first selector configured to select one of a first reference voltage and a first correction reference voltage, based on a first determination value of data at a past time of a first adjacent channel;
- a first comparator configured to compare a difference between a voltage selected from the first reference voltage and the first correction reference voltage, and a second reference voltage, with an input voltage at a current time of a target channel, wherein the input voltage is a differential signal comprising a first input voltage and a second input voltage;
- and
- a first output unit configured to determine an output voltage at the current time of the target channel, based on a comparison result of the first comparator.
