The future of ‘extremely’ energy-efficient circuits

Science Daily  September 18, 2019
Information communication technology is projected to account for 20% of total energy consumption in the United States by 2020. To reduce energy consumption while improving efficiency, an international team of researchers (Japan, USA – Northeastern University) used Adiabatic Quantum-Flux-Parametron (AQFP) to replace direct current with alternating current which acts as both the clock signal and the power supply — as the current switches directions, it signals the next time phase for computing. According to the researchers it could improve conventional communication technologies with currently available fabrication processes. They developed a computation logic that takes the high-level understanding of processing and how much energy a system uses and dissipates and describes it as an optimized map for each gate within the circuit model. The approach also compensates for the cooling energy needed for superconducting technologies and reduces the energy dissipation by two orders of magnitude…read more. Open Access TECHNICAL ARTICLE
