    • A control circuit for a read operation of a SERDES (SERializer and DESeriallizer) type semiconductor memory apparatus is disclosed that includes a first delay unit that is configured to generate and output a first delay signal to a first global input/output line driver by receiving a sensing-enable signal ‘IOSTB’, and to generate and output a second delay signal to a second global input/output line driver by receiving the sensing-enable signal. The first delay unit generates the second delay signal by delaying the sensing-enable signal in synchronization with a clock. The semiconductor memory apparatus also includes a second delay unit configured to generate a pipe latch control signal in response to the first delay signal and the second delay signal.

    • Provided is an algorithm analog-to-digital converter (ADC). The algorithm ADC obtains two digital outputs through different capacitor connections for one analog input signal and adds the digital output signals to obtain a final output value, so that a mismatch factor of the capacitor is removed to minimize a linearity limitation resulting from the capacitor mismatch. In addition, the algorithm ADC minimizes power consumption by making the operating frequency slow at a cycle requiring a high resolution and making the operating frequency fast at a cycle requiring a low resolution, i.e., outputting different operating clock frequencies according to a required resolution.
    • 提供了一种算法模数转换器(ADC)。 算法ADC通过不同的电容器连接获得两个数字输出,用于一个模拟输入信号,并将数字输出信号相加以获得最终输出值,从而消除电容器的失配因子,以最小化由电容器失配引起的线性限制。 此外,算法ADC通过使工作频率在需要高分辨率的周期中变慢,并使工作频率在需要低分辨率的周期(即,根据所需分辨率输出不同的工作时钟频率)的情况下将功率消耗最小化。
