کمپرسور مغناطیسی 4-2 با صرفه جویی در انرژی

In this paper, we present a hybrid MTJ/CMOS based low-power design of a 4-2 compressor. Furthermore, to gain more energy efficiency we implemented the proposed design with carbon nanotube field effect transistor (CNFET) technology and compared it with the MTJ/CMOS design. Simulations are performed at 45 nm and 32 nm CMOS technology with perpendicular anisotropy CoFeB/MgO MTJ model using Cadence Spectre simulator. Simulation results indicate that our hybrid MTJ/CMOS-based design has about two times lower power-delay product compared to the previous CMOS-based designs. Also, our MTJ/CNFET compressor has more than 3.5 times lower PDP compared to the CMOS based design.
