A pipelined ADC incorporates a precharged resistor-ladder DAC in a multi-bit front-end, achieving fast settling and allowing calibration of both dynamic and static gain errors. Using simple differential pairs with a gain of 5 as op amps and realized in 65-nm CMOS technology, the 10-bit ADC...
SAR-ADC 教程之三
Compared to the conventional switched capacitor SAR ADC structures, the settling speed of the current mode DAC is faster than the switched capacitor counterpart. As a proof of concept, this current mode ADC is designed for an overall resolution of 10bit over a Nyquist band from DC to 75MHz....
针对现代高速通信系统的应用场合，论文设计了一款10bit 500MS/s的Pipeline-SAR ADC，其系统架构为两级结构，两级SAR ADC都实现6bit的数据量化，级间放大器提供4倍增益，设置2bit 级间冗余。在第一级SAR ADC中，提出了一种基于自关断比较器的非环路（Loop-unrolled）结构，在每位比较完成后，通过自关断信号将当前...

国内流水线ADC研究起步较晚,加上国外对我们技术垄断,国内的ADC研究多停留在几十MHZ, 精度多在10bit以下,而且主要集中在全并行,积分型,逐次逼近型等低精度高速或者高速低精度的结构 上。高速高精度的研究成果不多见。这严重限制了我国在集成电路设计和系统集成方面的发展。 随着集成电路工艺不断向深亚微米发展,晶体...
