A High Speed Low Power Modulo 2ⁿ + 1 Multiplier Design using Carbon-Nanotube Technology
Modulo 2n + 1 multiplier is one of the critical components in the area of digital signal processing, residue arithmetic, and data encryption that demand high-speed and low-power operation. In this paper, a new circuit implementation of a high-speed low-power modulo 2n + 1 multiplier is proposed. It has three major stages: partial product generation stage, partial product reduction stage, and the final adder stage. The proposed structure introduces a new MUX-based compressor in the partial product reduction stage to reduce power and increase speed, and in the final adder stage, the Sparse-tree-based inverted end-around-carry adder reduces the number of critical path circuit blocks, also avoids wire interconnection problem. The proposed multiplier is implemented using both 32nm CNTFET (Carbon-Nanotube FET) and bulk CMOS technology for performance comparison. The CNTFET-based design dramatically decreases the PDP (Power Delay Product) of the circuit. The simulation results demonstrate that the power consumption of CNTFET-based multiplier is at average 5.72 times less than its CMOS counterpart, while the PDP of CNTFET is 94 times less than the CMOS one.
