A Full Adder Cell Based on MOSFET Technology to apply in Arithmetic circuits

In this paper, a full adder cell based on a parallel design using MOSFET ‎technology is presented. The main goal of designing this full adder cell is to reduce ‎critical path delay in adder circuits. The proposed design by reduces length of data ‎path and positively, affects speed and power consumption parameters. In order to ‎evaluate the proposed full adder cell, several simulations are performed in ‎different load capacitors, frequencies and temperatures using HSPICE in ۳۲nm ‎CMOS technologies. The proposed full adder cells were compared with eight other ‎full adder cells using ۴-bit Ripple Carry Adder (RCA) and ۸-bit RCA circuits in ‎power consumption, speed, and Power Delay Product (PDP) parameters. The ‎obtained results indicate that the proposed design is faster than other designs due ‎to a shortened data path. The results of the simulations confirm the higher efficiency ‎of the proposed full adder cell with respect to other designs. ‎
