Design of a Power Efficient Model of PWM Generator for Green Communication using High Performance FPGAs

This paper will focus on promoting the ideas of green communication Pulse Width Modulation (PWM) generator is used to control the power transfer in any communication model. It is one of the most crucial parts of an electrical circuit. Our main focus in this research work is to develop an energy and power-efficient PWM generator by using Field Programmable Gate Array (FPGA) logic to elevate green communication. Our main focus in this research work is to develop an energy and power-efficient PWM generator by using Field Programmable Gate Array (FPGA) logic to elevate green communication. In order to make the PWM suitable for GC, we have implemented the design on VIVADO ISE from Xilinx. The power analysis as well as resource utilization are targeted on three different FPGAs. Different IO standards of Stub Series Terminated Logic (SSTL) family are explored at different FPGA’s. Power analysis is deployed on the 7 series FPGAs of 3 different categories i.e., Spartan 7 (channel length = 28 nm), Kintex 7 (channel length = 20 nm) and ultra scale Zynq 7 (channel length = 16 nm). It can be concluded from power analysis that SPARTAN-7 device is the most powerefficient and ZYNQ Ultra scale+utilizes the highest amount of power. However, KINTEX-7 Ultrascale device lies in the middle of both these devices as far as power consumption is concerned. There is a reduction of 43.07 % TP consumption for SPARTAN-7 device with SSTL135 IO when equated with ZYNQ Ultra scale+ with SSTL18_I IO. Also, it can be observed from sections 5.1, 5.2 and 5.3 that there is more contribution of DP in TP consumption than SP. Hence the device utilizes additional power when it is in active state than static state. Since PWM generator is an integral part of data and wireless communication, it should require less power for proficient transmission and wellorganized green computing and communication
