  • 射频集成电路设计John Rogers(Radio Freq

    Radio Frequency Integrated Circuit Design I enjoyed reading this book for a number of reasons. One reason is that itaddresses high-speed analog design in the context of microwave issues. This isan advanced-level book, which should follow courses in basic circuits andtransmission lines. Most analog i ...

  • 计算FR4上的差分阻抗(PDF)

    Calculation of the Differential Impedance of Tracks on FR4 substrates There is a discrepancy between calculated and measured values of impedance for differential transmission lineson FR4. This is especially noticeable in the case of surface microstrip configurations. The anomaly is shown tobe due to ...

  • MR16 LED驱动MR16 LED灯与电子变压器兼容

    Abstract: There are differences between the operation of low-frequency AC transformers and electronic transformersthat supply current to MR16 lamps, and there are also differences in the current draw for MR16 halogen lamps andMR16 LED lamps. These contrasts typically prevent an MR16 LED lamp from ...

  • 为您的FPGA选择合适的电源

    Abstract: There are many things to consider when designing a power supply for a field-programmablegate array (FPGA). These include (but are not limited to) the high number of voltage rails, and thediffering requirements for both sequencing/tracking and the voltage ripple limits. This application n ...

  • 利用高压看门狗定时器加强汽车安全系统

      Abstract: As electronic systems take over many of the mechanical functions in a car—ranging from engine timing to steering andbraking—there is a growing concern about fault tolerance. There should not be a single point of failure that would prevent a car fromat least "limping" ...

  • 光纤激光器的电流源分析

      A large group of fiber optic lasers are powered by DCcurrent. Laser drive is supplied by a current source withmodulation added further along the signal path. Thecurrent source, although conceptually simple, constitutesan extraordinarily tricky design problem. There are anumber of practica ...

  • 基于C8051F310的山路转弯预防警示系统

    针对盘山路存在的转弯盲区,即在转弯时司机无法得知弯路对面是否有车辆通过,设计一种基于C8051F310的山路转弯预防警示系统。该系统利用一阶滤波算法检测山路转弯时是否有车辆通过。运用该算法可增强系统检测的实时性,提高检测机动车辆的灵敏度,同时大大减少环境温度对检测的干扰。试验表明该系统能够正确指示出在山路转 ...
