Erratum to A 1-V 140- W 88-dB Audio Sigma-Delta Modulator in 90-nm CMOS Libin Y
论文更正了图21的错误，并提供了正确的测量结果图。
1-V 140-μW 88-dB
音频Sigma-Delta调制器CMOSSNRSNDR
▸创新点1：该论文提出了一种在90-nm CMOS工艺下实现的1-V 140-μW 88-dB音频Sigma-Delta调制器，通过优化电路设计和功耗管理，显著降低了功耗并提高了信噪比（SNR）和信号噪声失真比（SNDR）。
▸创新点2：论文中采用了创新的Sigma-Delta调制器架构，通过改进量化器和反馈环路设计，实现了在低电压（1-V）下的高性能音频信号处理，适用于便携式音频设备。
▸创新点3：通过详细的实验验证，论文展示了调制器在输入幅度变化时的稳定性能，SNR和SNDR的测量结果证明了其在高动态范围音频应用中的优越性。
▸创新点4：论文还探讨了在纳米级CMOS工艺中实现高精度模拟电路的挑战，并提出了一些针对工艺变化的补偿技术，进一步提高了电路的可靠性和一致性。
