Optical wireless communication is an emerging and dynamic research and development area that has Generated a vast number of interesting solutions to very complicated communication challenges. For example, high data rate, high capacity and minimum interference links for short-range communication for inter-building communication, computer-to-computer communication, or sensor networks. At the opposite extreme is a long-range link in the order of millions of kilometers in the new mission to Mars and other solar system planets.

The planarization technology of Chemical-Mechanical-Polishing (CMP), used for the manufacturing of multi- level metal interconnects for high-density Integrated Circuits (IC), is also readily adaptable as an enabling technology in MicroElectroMechanical Systems (MEMS) fabrication, particularly polysilicon surface micromachining. CMP not only eases the design and manufacturability of MEMS devices by eliminating several photolithographic and film issues Generated by severe topography, but also enables far greater flexibility with process complexity and associated designs.

電子書-RTL Design Style Guide for Verilog HDL540頁A FF having a fixed input value is Generated from the description in the upper portion of Example 2-21. In this case, ’0’ is output when the reset signal is asynchronously input, and ’1’ is output when the START signal rises. Therefore, the FF data input is fixed at the power supply, since the typical value ’1’ is output following the rise of the START signal. When FF input values are fixed, the fixed inputs become untestable and the fault detection rate drops. When implementing a scan design and converting to a scan FF, the scan may not be executed properl not be executed properly, so such descriptions , so such descriptions are not are not recommended. recommended.[1] As in the lower part of Example 2-21, be sure to construct a synchronous type of circuit and ensure that the clock signal is input to the clock pin of the FF. Other than the sample shown in Example 2-21, there are situations where for certain control signals, those that had been switched due to the conditions of an external input will no longer need to be switched, leaving only a FF. If logic exists in a lower level and a fixed value is input from an upper level, the input value of the FF may also end up being fixed as the result of optimization with logic synthesis tools. In a situation like this, while perhaps difficult to completely eliminate, the problem should be avoided as much as possible.

如果在調(diào)諧器或電視機(jī)附近使用本機(jī)或任何其他使用微處理器的電子設(shè)備，則可能會產(chǎn)生圖像的噪聲或干擾。如果發(fā)生這種情況，請采取以下步驟將本機(jī)安裝在盡可能遠(yuǎn)離調(diào)諧器或T的地方。遠(yuǎn)離調(diào)諧器或T，遠(yuǎn)離本機(jī)的電源線和輸入/輸出連接電纜。尤其在使用室內(nèi)天線或300歐姆饋線。我們建議使用室外天線和75 Q / ohm同軸電纜Noise or disturbance of the picture may be Generated if this unit or any other electronic equipment using microprocessors is used near a tuner or TV If this happens, take the following stepsInstall this unit as far away as possible from the tuner or T Run the antenna wires from the tuner or T away from this unit ' s power supply cord and input/output connection cables. Noise or disturbance tends to occur particularly when using indoor antennas or300 ohm feeder wires. We recommend using outdoor antennas and 75 Q/ohm coaxial cables

為解決移相全橋電路驅(qū)動及相角控制問題,設(shè)計了一種數(shù)字控制的移相全橋驅(qū)動電路.以TPL521為光耦隔離、IR2110為柵極驅(qū)動芯片.由DSP產(chǎn)生PWM信號,經(jīng)過光耦隔離和邏輯電路后送至IR2110進(jìn)行相角控制.文章對IR2110驅(qū)動電路原理進(jìn)行分析及參數(shù)進(jìn)行設(shè)計,對TMS320F28335進(jìn)行設(shè)置并給出部分代碼.實驗結(jié)果表明：通過TMS320F28335可產(chǎn)生的不同相角的PWM波形,滿足了移相全橋?qū)Σ煌嘟强刂频囊?In order to solve the problem of phase-shifted full-bridge circuit driving and phase angle control,a digitally controlled phaseshifted full-bridge driving circuit was designed. TPL521 optocoupler isolation,IR2110 gate driver chip. PWM signals are Generated by the DSP and sent to the IR2110 for phase angle control after optocoupler isolation and logic circuits. This text carries on the analysis to the principle of IR2110 drive circuit and parameter design,set up and give out some code to TMS320F28335. The experimental results show that the PWM waveforms with different phase angles Generated by TMS320F28335 can meet the requirements of phase-shifted full-bridge control for different phase angles.
