摘要

本文介绍了一种基于CMOS技术的9位连续逼近寄存器模拟数字转换器(SAR-ADC)设计,特别是用于汽车工业传感器应用的I4T, 0.35 μm, 45 V。本文介绍了SAR-DAC的各个模拟元件:比较器、R-2R数模转换器(DAC)和运算放大器(OPA)。在模拟设计环境Cadence Virtuoso中验证了SAR-ADC的功能和参数。本文给出了所设计SAR-ADC的参数。

A high speed middle accuracy 9-bit SAR-ADC in 0.35-μm CMOS for sensor application in automotive industry
This paper describes a 9-bit Successive Approximation Register Analog to Digital Converter (SAR-ADC) design in CMOS technology, particularly I4T, 0.35 μm, 45 V, used in automotive industry for sensor application. There are the individual analogue components of the SAR-DAC descibed in this paper: the Comparator, the R-2R Digital to Analog Converter (DAC) and the Operational Amplifier (OPA). The functionality and the parameters of the SAR-ADC were verified in analog design environment Cadence Virtuoso. The parameters of the designed SAR-ADC are published in this paper.
