This paper presents a new method to reduce consumption power in flash ADC in 65nm CMOS technology. This method indicates a considerable reduction in consumption power, by removing comparators memories. The simulations used a frequency of 1 GHZ, resulting in decreased consumption power by approximately 90% for different processing corners. In addition, in this paper the proposed method was desig...
