Analog to digital converters are crucial components in many communication, signal processing systems and image capturing systems. The goal of this project was to design a high speed, low power 12-bit, Analog-to-Digital Converter (ADC) in CMOS (Complementary Metal-Oxide-Semiconductor) 0.18micron technology that makes it suitable for video application. For designing the particular ADC a bottom up hierarchical method is adopted. First according to the specification, the design of aspect ratio of the transistors used in the authors design is done.
