Approximate parallel prefix adders (AxPPA) are a type of circuit that can perform addition operations on binary numbers with high speed and low power consumption with less area. These circuits provide approximate results, which means that they sacrifice accuracy for efficiency. This trade off makes them ideal for use in applications where speed is more important than precision. In recent years, th...Show More

Owing to the high conversion rate along with low power consumption, flash ADCs are the most extensively used ADCs for high frequency applications, however their precision is modest. To construct a high-speed low power flash ADC, the comparator forms the most significant block, hence it must be designed in such a manner that it consumes less power and has a low delay. Proposed comparator has a dela...Show More
