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 order to save more energy.
