System having correction unit and correcting method thereof
First Claim
1. A system comprising:
- a target unit to be corrected; and
a correction unit configured to perform binary search of a correction value with which an output of the target unit gets closer to a reference value and feeds back the correction value to the target unit, whereinthe correction unit is configured to perform additional comparison for comparing a first output of the target unit and a second output of the target unit and for selecting a first or second correction value corresponding to the first or second output closer to the reference value, the first output corresponding to the first correction value searched by the binary search, the second output corresponding to the second correction value that is adjacent to the first correction value, a voltage relationship to the reference value of the second output being opposite to that of the first output,wherein the correction unit is configured to feed back the selected correction value to the target unit.

Abstract
A system has a corrected unit, and a correction unit that performs binary search of a correction value with which an output of the corrected unit gets close to a reference value and feeds back the correction value to the corrected unit. The correction unit performs the additional comparison for comparing a first output of the corrected unit corresponding to a first correction value searched by the binary search and a second output, which is an output of the corrected unit corresponding to a second correction value that is adjacent to the first correction value and is an output that the voltage relationship to the reference value is opposite to the first output, and for selecting the first or second correction value corresponding to the first or second output closer to the reference value, and feeds back the selected correction value to the corrected unit.

11. A system comprising:
-
a target unit to be corrected and to which a differential signal is inputted and which outputs a differential signal; and a correction unit configured to perform binary search of a correction value such that a difference of the differential output signal outputted when a difference of the differential input signal has zero potential gets closer to a reference value zero and feeds back the correction value to the target unit, wherein the correction unit is configured to perform additional comparison for comparing a first differential output signal of the target unit and a second differential output signal of the target unit, and for selecting a first or second correction value corresponding to the first or second differential output signal with the difference being closer to the reference value zero, the first differential output signal corresponding to the first correction value searched by the binary search, the second differential output signal corresponding to the second correction value that is adjacent to the first correction value, a voltage relationship of the second differential output signal being opposite to that of the first differential output signal, wherein the correction unit is configured to feed back the selected correction value to the target unit. - View Dependent Claims (12, 13)

14. A correcting method for a target unit in which an output of the target unit is monitored and a correction value to be fed back to the target unit is searched, comprising:
-
a binary search in which a correction value with which an output of the target unit gets closer to a reference value is binary-searched; an additional comparison in which a first output of the target unit is compared with a second output, which is an output of the target unit and a first or second correction value corresponding to the first or second output closer to the reference value is selected, the first output corresponding to the first correction value searched by the binary search, the second output corresponding to the second correction value that is adjacent to the first correction value, a voltage relationship to the reference value of the second output being opposite to that of the first output; and a feedback in which the selected correction value is fed back to the target unit.
