Scaling ADC Architectures for Mobile & Multimedia SoCs at 28-nm & Beyond

This white paper compares the attributes of common ADC architectures, including the Successive Approximation Register (SAR)-based architecture, for use in medium- and high-speed 28-nm ADCs. It describes advantages of the SAR-based architecture that reduce power consumption and area usage for mobile and multimedia SoCs. Finally, it presents the DesignWare SAR-based ADC family for 28-nm and explains how it benefits from advanced process nodes through adherence to the area and power scaling paradigms of digital circuitry.
