Abstract: PURPOSE: A method for eliminating input quantization effect is provided to obtain asymptotic stability of a system by reducing a quantization error without controlling a parameter or adding the hardware. CONSTITUTION: A control value for stabilizing a system is determined when changing a quantization level of the system input within one level(S100).

Abstract: An apparatus and a method for converting flash analog to digital are provided to reduce a data error generated at a high speed operation by increasing a window of an output signal of a plurality of preambles. A flash analog-to-digital converter(100) includes a reference voltage generator(110), a reference clock generator, an amplifier, a latch unit, a signal processor(150), a bubble error remover, and an encoder(170). The reference voltage generator generates the plurality of reference voltages. The plurality of pre-amps amplify and output the difference between an analog input signal and the plurality of reference voltages. The signal processor includes a plurality of window expansion units. The plurality of window expansion units increase the window of the output signal of the plurality of pre-amps as much as the predetermined size and output the increased window. The encoder encodes the output signal of the plurality of window expansion unit and outputs the digital signal.
