In this paper, the authors present the design of 6-bit flash Analog to Digital Converter (ADC) using the new Variable Switching Voltage (VSV) comparator. In general, flash ADCs attain the highest conversion speed at the cost of high power consumption. By using the new VSV comparator, the designed 6-bit flash ADC exhibits significant improvement in terms of power and speed of previously reported flash ADCs. The simulation result shows that the converter consumes peak power 2.1mW from a 1.2V supply and achieves the speed of 1GHz in a 65nm standard CMOS process.
