Comparative analysis of low power novel encoders for Flash ADC in 45nm technology

The electronics world is faced with various challenges when attempting to integrate analog signals with discrete or digital systems. The ADC is not a new concept b y any means, but is still a topic of interest when it comes to technology due to its inevitable necessity in many systems being used today. Power consumption in ICs was always a challenging issue. Most of the technology emphasizes on speed, accuracy, less power consumption. In almost all digital functioning, encoders are mandatory. Decreasing power consumption in an encoder is an area of strong desire. In this paper, we have designed two novel ultra low power encoders for Flash ADC application and also show its comparison with previous encoder available in literature. The work has been done on Tanner tool v15 in 45 nm technology with various DC voltage supplies.
