System-on-a-chip(SOC) requires the integration of analog circuits and digital circuits on a single chip. The technology compilable, performance optimized A/D converter (ADC) is an very important block as the bridge of the analog world to the digital section in SOC. It is important and necessary to research ADC with high speed, high resolution, low power
