With cascading two XNOR cells, the sum of two inputs is achieved. Regarding to advantages of m-GDI XNOR cell, we constructed the adder cell based on this architecture. The simulation results show that the power consumption of the adder cell designed with GDI technology is 12.993 μw, whereas for this cell designed with m-GDI technology is 4.1628 μw, which both are designed at 0.18 um technology. Moreover, simulation results in 90 nm CMOS technology for m-GDI adder cell show average power consumption of 0.90262 μw and 6.3222 μw in 200 MHz and 2GHz, respectively.展开更多
