摘要

本文提出了一种多带宽10位SAR模数转换器(ADC),该ADC带有带边组合的数字锁延环(DDLL)电路,用于自时钟生成。本设计的ADC电路避免了外部时钟信号进行采样,从模拟输入信号中产生时钟,工作频率范围广。提出的ADC设计能够在10Ksps到1.8Msps的输入频率范围内工作,最大采样时钟为40MHz。所提出的ADC已在具有DNL的标准65nm CMOS技术上设计并验证了后布局仿真

A Multiple-Bandwidth 10-bit SAR Analog to Digital Converter
In this paper, a multi bandwidth 10-bit SAR analog to digital converter (ADC) with edge-combiner digital delay locked loop (DDLL) circuit for self clock generation is proposed. The ADC circuit in the proposed design avoids external clock signal for sampling and clock is generated from analog input signal for a wide range of frequency operation. The proposed ADC design is capable of operating over the input frequency range of 10Ksps to 1.8Msps with 40MHz maximum sampling clock. The proposed ADC have been designed and verified for post layout simulations in standard 65nm CMOS technology which has DNL
