ADC 芯片向更高 速度,更高精度,更高能效的方向发展.噪声整形(noise-shaping)逐次逼近型(SAR)模数转换器因其电路结构简单,能够在实现 小面积的同时达到较高的转换精度,与低功耗,高精度的应用场景相适应,逐渐成为当前集成电路设计中的研究热点.本文对当前 国内外 noise-shaping SAR ADC 的相关研究进行充分的调研,从...
传统模数转换器难以通过单一架构同时满足高精度,低功耗的要求,近年来,一种新型模数转换器混合架构——噪声整形逐次逼近型模数转换器(Noise-shapingSARADC)结合了逐次逼近型模数转换器(SARADC)与Σ-ΔADC架构的优点,能够同时实现高精度,低功耗的性能.然而凭借混合架构的优势,目前Noise-shapingSARADC的设计一般也难以实现...
In this way, the required total capacitance of the ADC is reduced more than 96% compared to a 10-bit conventional SAR (CSAR) ADC. Also, due to noise-shaping property the comparator specifications are relaxed. The ADC is designed and simulated in 90nm CMOS technology with HSPICE simulator. ...
