摘要

为了解决低电压下锁存误差问题，我们改进了噪声整形信号流，并制作了一个1.2 v, 16位摆幅抑制音频a /D转换器。该变换器的S/(N+THD)为91.5 dB, DR为94.0 dB，低功耗为6.5 mW。

1.2-v, 16-bit Audio A/d Converter With Suppressed Latch Error Noise

We have improved the noise-shaping signal flow in order to solve the latch error problem at low voltage supply and have fabricated a 1.2-V, 16-bit swing-suppression A/D converter for audio. The converter achieves S/(N+THD) of 91.5 dB, DR of 94.0 dB, and low power consumption of 6.5 mW.
