The goal of this trend is to have a single-chip solution, in which analog and digital circuits are placed on the same die with advanced CMOS technology. The complete integration of a system may include a digital processor, memory, ADC, DAC, signal conditioning amplifiers, frequency translation, filtering, reference voltage/current generator, etc. Although advanced fabrication technology benefits digital circuits, it poses great challenges for analog circuits. For instance, the scaling of CMOS devices degrades important analog performance such as output resistance, lowering amplifier gain. Simply lowering the power supply voltage in analog circuits does not necessarily result in lower power dissipation. The many design constraints common to the design of analog circuits makes it difficult to curb their power consumption. This is especially true for already complicated analog systems like ADCs; reducing their appetite for power requires careful analysis of system requirements and special strategies. This thesis describes a 10bits 100-MS/s low-voltage pipelined analog-to-digital converter (ADC), which consists of 8-stage-pipelined low resolution ADCs and a 2-bit flash ADC. Several critical technologies are adopted to guarantee the resolution and high sampling and converting rate such as 1.5bits per stage conversion, digital correction logic, folded-cascode gain-boosted amplifiers and so on.

碩士 === 國立中山大學 === 資訊工程學系研究所 === 98 === The trend toward higher-level circuit integration is the result of demand for lower cost and smaller feature size.

The complete integration of a system may include a digital processor, memory, ADC, DAC, signal conditioning amplifiers, frequency translation, filtering, reference voltage/current generator, etc.
Although advanced fabrication technology benefits digital circuits, it poses great challenges for analog circuits. For instance, the scaling of CMOS devices degrades important analog performance such as output resistance, lowering amplifier gain.

This thesis describes a 10bits 100-MS/s low-voltage pipelined analog-to-digital converter (ADC), which consists of 8-stage-pipelined low resolution ADCs and a 2-bit flash ADC.
