随着电子技术的快速发展，嵌入式系统已经成为热点。嵌入式系统大量应用在自动控制、工业设备和家用电器当中。当前应用的产品常以嵌入式处理器的形式出现，常用的如PDA、交换机、路由器等。嵌入式的广泛应用大大提高了人们的生活水平。位置敏感探测器（Position Sensible Detector）是一种基于半导体PN结横向光电效应的光电 ...

Abstract: The MAX9930–MAX9933 family of RF controllers and detector can be used in a wide variety of applications. Anideal application is cable television (CATV) over fiber, where either a RF controller or a RF detector controls the gain of atransimpedance amplifier (TIA). This application n ...

  Automobile electronic systems place high demands ontoday’s DC/DC converters. They must be able to preciselyregulate an output voltage in the face of wide temperatureand input voltage ranges—including load dump transientsin excess of 60V and cold crank voltage drops to 4V. Thec ...

以89S52单片机和EP1C6Q240C8型FPGA为控制核心的多功能计数器，是由峰值检波、A/D转换、程控放大、比较整形、移相网络部分组成,可实现测量正弦信号的频率、周期和相位差的功能。多功能计数器采用等精度的测量方法，可实现频率为1Hz～10MHz、幅度为0.01～5Vrms的正弦信号的精确测频，以及频率为10Hz～100kHz、幅度为0.5～5Vrm ...

The Maxim Integrated 71M6541-DB REV 3.0 Demo Board is a demonstration board for evaluating the 71M6541 device for single-phase electronic energy metering applications in conjunction with the Remote Sensor Inter-face. It incorporates a 71M6541 integrated circuit, a 71M6601 Remote Interface IC, periph ...

位置敏感探测器PSD（Position Sensitive Detector PSD）具有位置分辨精度高（可达1～2 μm）、输出实时性好（响应时间约几微秒）、系统简洁的特点，在位置探测及相关领域内获得了广泛的应用；但PSD的输出信号小，易受到电路噪声的影响，若要充分发挥其性能，则需要高精度、高稳定度、低噪声的测量电路。针对PSD这种较高的 ...

Abstract: How can an interface change a happy face to a sad face? Engineers have happy faces when an interface works properly.Sad faces indicate failure somewhere. Because interfaces between microprocessors and ICs are simple—even easy—they are oftenignored until interface failure caus ...
