An effective 6-bit flash ADC using low power CMOS technology

Abstract

In present day communication technology, Digital communication plays a tremendous role in effective power utilization of resources. In many aspects of Digital communication, both wired and wireless communication technologies are covered. To implement a digital communication system, Analog to Digital Conversion is must as the source of many systems is analog in nature. The effectiveness of Digital communication systems relay on speed of ADC. For this, there exist many types of ADCs such as Counter type ADC, Successive approximation type ADC, Flash Type ADC and Wilkinson type ADC. Among them Flash Type ADC has high ADC rate but with a drawback of high power consumptions. This drawback of high power consumption for Flash Type ADC is over come in our proposed method where a new 6-bit Flash Type ADC with less complexity and a conversion rate of 1-GS/s is implemented which results in low power consumption using low power CMOS technology. Here we use tools such as Micro Wind and Digital Schematic.
