FinFET based Design and Performance Analysis of Nano-processor for Low Area, Low Power and Minimum Delay using 32nm

Abstract

The recent technologies in VLSI chips has grown in terms of scaling of transistor and device parameters but still there is a challenging task for controlling of current between source and drain terminals. For effective control of device current, the FinFET transistors have come into VLSI chip manufacturing, through which current can be effectively controlled. This section addresses the issues present in CMOS technology and majorly concentrated on proposed 4-bit Nano processor using FinFET 32nm technology by using Cadence Virtuoso software tool. In the proposed Nanoprocessor design, the first portion of the design is done using 4bit ALU which includes all basic and universal gates, high speed adder, multiplier and multiplexer. The Carry Save Adder (CSA) and multiplier are the major sub component which can optimize the power consumption and area reduction. The second portion of the proposed Nano processor design is 4-bit 6T SRAM and encoder and decoder and also using Artificial Neural Network (ANN). All these sub components are designed at analog transistors (Schematic level) through which the Graphic Data System (GDS-II) is generated through mask layout design. Finally, the verification and validation are done using DRC and LVS and at the last chip level circuit is generated for chip fabrication. The ALU is designed by using CMOS inverters and the designed ALU schematic is simulated through 32nm FinFET using technological library and compared with CMOS technology which is simulated through 32nm CMOS library (without FinFET). The power consumption of AND, OR, XOR, NOT, NAND gates, SRAM, Encoder, Decoder and ANN are 36.09nW, 64.970nW, 61.13nW, 33.31nW, 37.45nW, 32.5% with optimization in power dissipation of 47% along with optimization in leakage current, with 2.68uW, 1.98uW and 7.5% improvement in power consumption and 0.5% information loses are compressed subsequently respectively. The basic gates, universal gates, CSA, subtraction and MUX are integrated for 4-bit ALU design and its delay, power consumption and area are found to be 0.104nsec, 314.4uW and 56.8μsqm respectively.
