Abstract

Limit-cycle oscillation in noise-shaping D/A converters is one of serious problems because it interrupts their noise-shaping operation. We propose a new noise-shaping structure that prevents limit-cycle oscillation. We have used this structure in an audio D/A converter that we fabricated. The measured result shows that limit-cycle oscillation is prevented and noise-shaping operation is maintained even when the input data is real zero. This D/A converter achieves the S/N+THD of 101 dB.
一种防止限环振荡的四阶本地前馈D/A转换器
噪声整形型数模转换器的限环振荡是一个严重的问题,它中断了模数转换器的噪声整形工作。我们提出了一种新的防止极限环振荡的噪声整形结构。我们已经在我们制造的音频D/A转换器中使用了这种结构。测量结果表明,即使输入数据为实零,也能有效地防止极限环振荡,保持噪声整形运算。该D/A转换器的信噪比为101 dB。
