  • 干涉型光纤水听器信号解调方法研究

    光纤水听器自问世以来,在巨大的军事价值和民用价值推动下得到了迅速发展,已逐渐从实验室研究阶段走向工程应用。同时随着光纤水听器的不断发展,对水声信号的检测技术以及数字处理能力也提出了新的要求。论文在此背景下开展了一系列研究工作,并提出了利用FPGA(Field ProgrammableGate Array,现场可编程门阵列)实现光纤3×3耦合器解调算法的新思路。 目前干涉型光纤水听器的解调一般采用PGC(Phase GeneRated Carrier,相位生成载波技术)技术和基于3×3光纤耦合器干涉的解调技术。PGC技术在解调过程中引入了载波信号,它对采样率,激光器等的要求都较高,因此我们把目光投向3×3耦合器解调技术,文中对其解调原理进行了阐述,对采样率的确定进行了讨论,并对3×3耦合器三路输出不对称的情况进行了分析,最后在本文的结论部分提出了基于3×3耦合器解调的改良方案。 目前,光纤信号数字化解调的硬件实现采用DSP(Digital Signal Process,可编程数字信号处理器)信号处理机,与之相比,FPGA解调具有速度快、资源占用少、易于扩展等优势。本文对FPGA与DSP、ASIC(application-specificintegrated circuit,专用集成电路)实现方案进行了对比,分析了适合利用FPGA实现的算法所应具备的特征;介绍了3×3耦合器解调算法中各个模块的设计情况;分析了系统的工作情况,硬件的构造及芯片的选择,最后验证了利用FPGA可以实现3×3耦合器解调算法。

  • 利用数字电位器调整并校准升压型DC-DC转换器

    The purpose of this application note is to show an example of how a digital potentiometer can be used in thefeedback loop of a step-up DC-DC converter to provide calibration and/or adjustment of the output voltage.The example circuit uses a MAX5025 step-up DC-DC converter (capable of generating up to 36V,120mWmax) in conjunction with a DS1845, 256 position, NV digital potentiometer. For this example, the desiredoutput voltage is 32V, which is GeneRated from an input supply of 5V. The output voltage can be adjusted in35mV increments (near 32V) and span a range wide enough to account for resistance, potentiometer and DCDCconverter tolerances (27.6V to 36.7V).

  • Active Filters

    Power conversion by virtue of its basic role produces harmonics due to theslicing of either voltages or currents. To a large extent the pollution in theutility supply and the deterioration of the power quality has been GeneRatedor created by non-linear converters. It is therefore ironic that power convertersshould now be used to clean up the pollution that they helped to create inthe first place.In a utility system, it is desirable to prevent harmonic currents (which resultin EMI and resonance problems) and limit reactive power flows (whichresult in transmission losses).Traditionally, shunt passive filters, comprised of tuned LC elements andcapacitor banks, were used to filter the harmonics and to compensate forreactive current due to non-linear loads. However, in practical applicationsthese methods have many disadvantages.

  • 基于FPGA的高度集成DCDC稳压器

      In a recent discussion with a system designer, the requirementfor his power supply was to regulate 1.5Vand deliver up to 40A of current to a load that consistedof four FPGAs. This is up to 60W of power that must bedelivered in a small area with the lowest height profi lepossible to allow a steady fl ow of air for cooling. Thepower supply had to be surface mountable and operateat high enough effi ciency to minimize heat dissipation.He also demanded the simplest possible solution so histime could be dedicated to the more complex tasks. Asidefrom precise electrical performance, this solution had toremovethe heat GeneRated during DC to DC conversionquickly so that the circuit and the ICs in the vicinity do notoverheat. Such a solution requires an innovative designto meet these criteria:

  • 高效LCD液晶照明技术

    In August of 1992 LTC published Application Note 49, “Illumination Circuitry for Liquid Crystal Displays.” One notable aspect of this event is that it GeneRated more response than all previous LTC application notes combined. This level of interest, along with significant performance advances since AN-49’s appearance, justifies further discussion of LCD backlighting circuitry.

  • PCA9544A 4channel I2C multiple

    The PCA9544A provides 4 interrupt inputs, one for each channeland one open drain interrupt output. When an interrupt is GeneRated byany device, it will be detected by the PCA9544A and the interruptoutput will be driven LOW. The channel need not be active fordetection of the interrupt. A bit is also set in the control byte.Bits 4 – 7 of the control byte correspond to channels 0 – 3 of thePCA9544A, respectively. Therefore, if an interrupt is GeneRated byany device connected to channel 2, the state of the interrupt inputs isloaded into the control register when a read is accomplished.Likewise, an interrupt on any device connected to channel 0 wouldcause bit 4 of the control register to be set on the read. The mastercan then address the PCA9544A and read the contents of thecontrol byte to determine which channel contains the devicegenerating the interrupt. The master can then reconfigure thePCA9544A to select this channel, and locate the device generatingthe interrupt and clear it. The interrupt clears when the deviceoriginating the interrupt clears.
