Power optimization of Pseudo Noise based optical transmitter using LVCMOS IO standard

In electronic devices when operating frequency is exceeded from its resonant frequency the power of the device increases drastically. Due to this, device reaches in dead zone and will not function anymore. In this work, power optimization is performed for Pseudo Noise sequence based optical transmitter. The PN generator for optical transmitter is designed using linear shift registered generator method. Furthermore, energy efficient design for the PN generator is also proposed using low voltage complementary metal oxide semiconductor (LVCMOS) IO standard available on FPGA virtex-6 board. The PN generator is operated at different frequencies such as 100 MHz, 1 GHz, 10 GHz and 100 GHz and at different LVCMOS IO standard such as LVCMOS 12, 18, 15 and 25. The power reduction is achieved for frequencies using standards available on FPGA. Finally, power optimization is recorded for target device at 100 MHz 97.7%, for 1 GHz 98%, for 10 GHz 95% and for 100 GHz 95% using LVCMOS 12 in comparison with LVCMOS 25. This energy efficient PN generator can be integrated with other optical components to develop green optical communication system. Experiment is performed via Xilinx ISE14.7 design tool and FPGA vertex-6 board.
