    • A comparison system including a dynamic comparator, a background offset calibration circuit, and an asynchronous reset timing control circuit is presented. The background offset calibration circuit is coupled to the dynamic comparator, and generates calibration signals in response to reference switching control signals. Where calibration signals are used to calibrate the input refer offset of the dynamic comparator. The asynchronous reset timing control circuit is coupled to the dynamic comparator and the background offset calibration circuit, and generates a control clock signal and the reference switching control signals in response to the output signals of the dynamic comparator and a plurality of basic clock signals. During each clock cycle of the first basic clock signal, the control clock signal is used to control the dynamic comparator to perform two data comparison, one for the input refer offset and the other for a differential input signal.

    • A dynamic comparator with background offset calibration is provided. The dynamic comparator includes at least one input differential pair, a first back-to-back inverter, a second back-to-back inverter, and an integrator. The input differential pair includes two current branches, wherein one of the current branches has an input referred offset. The first back-to-back inverter determines which one of the two current branches has the input referred offset in response to a first clock signal and generates two control signals accordingly. The integrator generates two calibration voltages for the input differential pair in response to the two control signals, so as to calibrate the input referred offset. The second back-to-back inverter determines a difference between two input signals received by the input differential pair after the input referred offset is calibrated in response to a second clock signal and outputs two comparison signals accordingly.
    • 提供了具有背景偏移校准的动态比较器。 动态比较器包括至少一个输入差分对,第一背对背反相器,第二背对背反相器和积分器。 输入差分对包括两个电流分支,其中当前分支中的一个具有输入参考偏移。 第一背对背反相器确定两个电流分支中的哪一个响应于第一时钟信号而具有参考的输入偏移,并相应地产生两个控制信号。 积分器响应于两个控制信号为输入差分对产生两个校准电压,以校准输入参考偏移。 第二背对背逆变器确定在响应于第二时钟信号校准输入参考偏移之后由输入差分对接收的两个输入信号之间的差异,并相应地输出两个比较信号。
