應用於生醫系統之類比數位轉換器

Abstract

在世界各地的大多數已開發國家，人口老齡化是一個普遍觀察到的現象。而電機電子領域人將研究重點從消費性電子產品轉向生醫應用。在這個趨勢下，我們設計適合應用於生醫系統的類比數位轉換器。 在本論文的第二章，我們將先介紹類比數位轉換器的基本理論。 在本論文的第三章，我們介紹一種利用單調式切換電容以減少功耗的連續漸進式類比數位轉換器。 在本論文的第四章，我們介紹一個輔助牙醫師診斷、治療阻塞性睡眠呼吸中止症的生醫系統晶片。 這些晶片都是使用UMC 0.18um CMOS的製程實現。

Ageing population is a commonly observed phenomenon in most developed countries all over the world. Electrical engineers have turned their attention from consumer products to application in biomedical. We design ADCs that are suitable for biomedical application under this trend. In chapter 2, the fundamentals of analog-to-digital converters is introduced. In chapter 3 of this thesis, a low power successive approximation register analog-to-digital converter (SAR ADC) using monotonic switching procedure to decrease the power consumption is presented. In chapter 4 of this thesis, a biomedical system on chip (SoC) for smart oral appliance is introduced. These chips are fabricated in UMC 0.18 um CMOS process and the measurement results will be shown.
