Frequency Scaling Based Power Efficient Current Source Design on FPGA

Abstract

 Abstract: Power deficiency is one of the major problems that the whole world is facing now. This is happening because of the immense increase in the world's population and the global increase of industrialization. So in order to minimize the consumption of power, an energy efficient current source is designed with the help of Field Programmable Gate Array (FPGA). This work gives light on how the power variation takes place in a current source with an increase in frequency value. In this research work, the current source is implemented on 28 nanometers (nm) Airtx-7 FPGA. The work is demonstrated on Xilinx 14.1 ISE simulator. VHSIC Hardware Description Language (VHDL) is used for writing the code of current source. The frequency of current source with Airtx-7 FPGA is increased from 100MHz to 5GHz. It is analyzed that the total power consumption is less as the value of frequency is low. So it is always advisable to operate the device at a lower frequency range in orderto save more energy.

“…The selection of algorithms relies on considerations such as the extent of security needed, computational capability, and industry standards. Here [3,4] are some prominent encryption algorithms in use: Advanced Encryption Standard (AES): AES is a recognized as the standard by the National Institute of Standards and Technology (NIST),is a symmetric encryption algorithm designed to operate on fixed-size data blocks. It offers compatibility for key lengths of 192, or 256 bits.…”
