摘要： An analog-to-digital converter (ADC) (15) provides digital error correction. Parallel ADC stages are synchronously clocked to convert an analog input signal (A IN) into digital words; at least one of the digital outputs (D OUT) is encoded according to an error correction code. Decision logic circuitry (24) decodes a code word comprised of the concatenation of the digital outputs from the parallel stages, to derive a digital output from which the digital output word corresponding to the analog input signal can be derived. The decision logic circuitry (24) can provide an error signal used to correct the state of one or more bits of the digital output from one of the ADC stages, for the case of a systematic code; alternatively, the decision logic circuitry can directly decode the code word to provide the digital output. The architecture may be applied to stages in a pipelined ADC.
摘要翻译：模数转换器（ADC）（15）提供数字纠错。并行ADC级同步时钟，将模拟输入信号（A IN）转换为数字字; 数字输出（D OUT）中的至少一个根据纠错码进行编码。判决逻辑电路（24）对由并行级的数字输出的级联组成的码字进行解码，以导出数字输出，从该数字输出可以导出与模拟输入信号对应的数字输出字。对于系统代码，判决逻辑电路（24）可以提供用于校正来自ADC级之一的数字输出的一个或多个位的状态的误差信号; 或者，判决逻辑电路可以直接解码码字以提供数字输出。该架构可以应用于流水线ADC中的阶段。
