Abstract: When converting an analog signal to N-bit digital codes, high SNR (signal to noise ratio) by generating multiple N-bit codes from the same analog sample and averaging the N-bit codes. However, the entire N-bit code is determined only a single time, and only P-bit (P less than N) codes are generated. The P-bit codes may be averaged, and the N-bit code is corrected based on the average value to generate an accurate N-bit digital code. As P can be much less than N, the correction can be implemented in a few iterations, thereby enabling the ADCs to be implemented with a high throughput performance. Due to the correction, a high SNR may be attained as well.
Abstract translation: 通过从相同的模拟采样产生多个N位代码并对N位代码进行平均，将模拟信号转换为N位数字码，具有高SNR（信噪比）。 然而，整个N位代码仅被确定一次，并且仅产生P位（P小于N）个代码。 可以对P位代码进行平均，并且基于平均值校正N位代码以产生精确的N位数字代码。 由于P可以远小于N，所以可以在几次迭代中实现校正，从而使得能够以高吞吐量性能实现ADC。 由于校正，也可以获得高SNR。
