Low-Power High-Speed 8-bit Conditional Carry Adder (CCA) using Memristor Logic

摘要

Memristive frameworks or Memristors have obtained significant consideration due to the universality and high-speed performances, low- energy consumption to expedite data processing in real-time. This article consolidates the use of memristor for the implementation of digital logic gates, such as AND, OR and XOR. By employing memristor-based logic gates with reduced transistor counts, high-performance 8-bit Conditional Carry Adder (CCA) configuration is realized for low-power arithmetic systems. Memristor based 2x1 multiplexer is proposed utilizing Cadence Virtuoso environment of GPDK 90nm CMOS technology. In terms of power and energy-delay product, 54.64% - 96.56% and 78.37% - 99.71% improvement is observed by analyzing with the earlier reported works. By considering fixed 1V supply voltage, the power matrices for the configuration is achieved using Spectre simulation. Finally, a 16-bit CCA configuration is realized using 8-bit CCAs.
