10-bit 40MHZ Sampling Rate Pipelined Analog-to-Digital Converter

Abstract

随着通信技术的发展和数字产品的日益增长,作为连接模拟信号与数字信号的桥梁,ADC在信号处理中越显重要。ADC的种类多种多样,它们的结构限制了速度、精度以及功耗等各方面的性能。因此,不同的ADC在不同应用场合有着特定的优势和市场。流水式ADC由于其速度快、精度较高、功耗相对较小的原因广泛应用于数字通讯领域中。 ADC的速度得益于工艺尺寸的缩小,但是精度却受到了限制。在CMOS工艺中,尺寸下降导致了晶体管的本征增益的衰减;在深亚微米工艺中,器件的匹配系数不是很高,运放会产生较大的失调电压,电容也有可能会有较大的不匹配,这些都将限制了ADC的精度,这就要求ADC要具有模拟或者数字补偿电路。近年来,...With the development of communication technology and the growing number of digital products,ADC(Analog-to-Digital Converter) technology, the bridge between analog signal and digital signal, has become more and more important in signal processing.ADC technology has many different types with different performance in speed , precision, power consumption and so on. Therefore,each type of ADC has its s...学位:工学硕士院系专业:物理与机电工程学院物理学系_微电子学与固体电子学学号:1982008115303
