    Abstract: An analog-to-digital converter includes a comparison signal generation unit and a control unit. The comparison signal generation unit determines a logic level of a comparison signal by comparing an input signal with a selected reference signal based on a switch control signal in a first comparison mode, and by comparing a difference voltage with a ramp signal based on the switch control signal in a second comparison mode. The difference voltage is generated based on the input signal and the selected reference signal such that a level of the difference voltage is lower than a fine voltage level corresponding to a voltage level of the selected reference signal in the second comparison mode. The control unit generates the switch control signal based on the comparison signal and a mode selection signal.

    Abstract: In an apparatus and method for automatically correcting a design pattern in view of different process defects, defect characteristic functions that indicate frequencies of each process defect independent from one another are generated, and a normalization factor that indicates relationships between the defect characteristic functions is determined. A general defect characteristic function indicating a frequency of general defects is generated using the defect characteristic functions and the normalization factor. The general defect causes the same process failure as caused by each of the process defects. The design pattern is modified using the general defect characteristic function in such a manner that the frequency of the general defects is minimized when at least one portion of the design pattern corresponding to the model pattern is transcribed on the substrate. Accordingly, the whole design pattern may be automatically corrected based on the general defect characteristic function.
