Abstract
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.
