Abstract
A new type of analog-to-digital converter (ADC) called a level-crossing ADC (LC-ADC) has been proposed in recent years to reduce power consumption in biomedical applications. A LC-ADC saves power by performing a conversion only when the input signal crosses a pre-defined threshold, and does not operate if the input signal does not change. LC-ADCs are well-suited for biomedical applications which have slowly varying signals and require minimal power consumption. This project focuses on the design of a 1-bit switched-capacitor digital-to-analog converter (SC-DAC) for use in a new type of LC-ADC that consumes less power than traditional LC-ADCs. It saves power in part by replacing the conventional n-bit DACs used in traditional LC-ADCs with a 1-bit SC-DAC.
