Analog-to-Digital Converters (ADCs) are key design blocks and are currently adopted in many application fields to improve digital systems, which achieve superior performances with respect to analog solutions. Application such as wireless communication and digital audio and video have created the need for cost effective data converters that will achieve higher speed and resolution. Comparator is one of the main building blocks in most analog-to-digital converters. Many high speed analog to-digital converters, such as flash ADCs, require high-speed and low power comparators with small chip area.
