| 1 | Ultra-Low Power Small Size 5.8 GHz RF Transceiver Design for WiMAX/4G Applications显示文摘A state of the art ultra-low power small sized transceiver design has been proposed.This device consists of four blocks,including a frequency synthesizer(FS),a crystal oscillator(XO),transmitter and receiver attached with an antenna.It has been seen that wireless information technology and systems have played a vital role in the transformation of society in different aspects of life.Mobile wireless communications including WiMAX/4G have attracted researchers and developers.WiMAX/4G applications need a transceiver that can be used in the worst channel conditions,but with low power consumption and low input voltage at the 5.8 GHz frequency.The proposed transceiver operates on 1.2 V.The operating frequency,noise figure(NF)and receiver gain are 5.8 GHz,4.0 dB and 90 dB respectively.It is a highly compatible transceiver with all the 4G technologies.Implementation details and results have revealed that the proposed transceiver is much more efficient than the previously proposed transceivers in literature. | Muhammad Yasir Faheem Shuna'n Zhong Abid Ali Minhas Muhammad Basit Azeem | 2019 | Journal of Beijing Institute of Technology2019，28，1： | 0 |
| 2 | Ultra-Low Power 1 Volt Small Size 2.4 GHz CMOS RF Transceiver Design for Wireless Sensor Node显示文摘Ultra-low power transceiver design is proposed for wireless sensor node used in the wireless sensor network(WSN).Typically,each sensor node contains a transceiver so it is required that both hardware and software designs of WSN node must take care of energy consumption during all modes of operation including active/sleep modes so that the operational life of each node can be increased in order to increase the lifetime of network.The current declared size of the wireless sensor node is of millimeter order,excluding the power source and crystal oscillator.We have proposed a new 2.4 GHz transceiver that has five blocks namely XO,PLL,PA,LNA and IF.The proposed transceiver incorporates less number of low-drop outs(LDOs)regulators.The size of the transceiver is reduced by decreasing the area of beneficiary components up to 0.41 mm^2 of core area in such a way that some functions are optimally distributed among other components.The proposed design is smaller in size and consumes less power,<1 mW,compared to other transceivers.The operating voltage has also been reduced to 1 V.This transceiver is most efficient and will be fruitful for the wireless networks as it has been designed by considering modern requirements. | Muhammad Yasir Faheem Shun'an Zhong Abid Ali Minhas Muhammad Basit Azeem | 2018 | Journal of Beijing Institute of Technology2018，27，4： | 0 |
