Abstract
Devices and methods for detecting and correcting duty cycles are described. An input switching unit is configured to perform at least one of an operation of outputting differential input signals as a first combination of first and second output signals and an operation of outputting the differential input signals as a second combination of the first and second output signals, according to one of a plurality of control signals. A comparator is configured to receive the first output signal through a first input terminal thereof, to receive the second output signal through a second input terminal thereof, to generate duty detection signals by comparing the signal of the first input terminal and the signal of the second input terminal according to at least another one of the plurality of control signals, and to adjust an offset of at least one of the first input terminal and the second input terminal.
