應用於生醫系統之低功耗類比數位轉換器暨多功能神經刺激器

從以前到現今的社會，人類一直為了許多的疾病苦惱，無論現在還是未來，不變的是我們對生命的態度。因此，生醫方面的知識，需求將會越來越大。在這個趨勢之下，我們設計一個適合應用在生醫系統的類比數位轉換器。在本論文的第三章，我們介紹一種採用傳統架構的單端輸入連續漸進式類比數位轉換器。在本論文的第四章，我們介紹一套整合型的系統晶片— 刺激晶片，裡面是由各種電路所組合而成，其中也包含了類比數位轉換器。第三章的晶片是使用 TSMC 0.18um 1P6M CMOS的製程實現。第四章的晶片是使用 TSMC 0.35um 2P4M CMOS 的製程實現。

At our society from the previous to the present, we are always having trouble for many diseases. Whether now or future, it is unchangeable to our life attitude. Therefore, the demand of biomedical knowledge will get more and more. We design ADCs that are suitable for biomedical application under this trend. In Chapter 3 of this thesis, a low power single-ended SAR ADC is presented which uses conventional structure. In Chapter 4 of this thesis, a set of integrated system-on-chip, Stimulator, is presented which contains various circuits. One of them is ADC. The chip of chapter 3 is fabricated by TSMC 0.18u, 1P6M CMOS technology and the measurement results will be shown. The chip of chapter 4 is fabricated by TSMC 0.35u, 2P4M CMOS technology and the measurement results will be shown.
