位置敏感探測器PSD（Position Sensitive Detector PSD）具有位置分辨精度高（可達1～2 μm）、輸出實時性好（響應時間約幾微秒）、系統簡潔的特點，在位置探測及相關領域內獲得了廣泛的應用；但PSD的輸出信號小，易受到電路噪聲的影響，若要充分發揮其性能，則需要高精度、高穩定度、低噪聲的測量電路。針對PSD這種較高的使用要求，通過對其等效模型的分析，找到了影響位置分辨精度的主要因素，并提出了一種新形式的測量電路，減少了測量電路級數，降低了電路的噪聲以及測量電路內部的漂移，同時具有對位置測量非線性的校正功能。采用上述原理以S1880 PSD建立的位置測量系統的位置分辨達到2～3 μm。

ARM7硬件說明與開發 The ARM7 is a low-power, general purpose 32-bit RISC microprocessor macrocell for use in application or customer-specific integrated circuts (ASICs or CSICs). Its simple, elegant and fully static design is particularly suitable for cost and power-Sensitive applications. The ARM7’s small die size makes it ideal for integrating into a larger custom chip that could also contain RAM, ROM, logic, DSP and other cells.

TFIND searches for one or more strings (boolean AND) in a text file. TFIND reports all lines where the string(s) were found (or NOT found by option). The search can be limited to a field in a fixed field (i.e. column oriented) list. An extended search mode is available, where only letters and digits are relevant. Other options: case Sensitive search, alternative errorlevel with number of hits, header line with file name, LFN, custom prefix

The AP2406 is a 1.5Mhz constant frequency, slope compensated current mode PWM step-down converter. The device integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. It is ideal for powering portable equipment that runs from a single cell lithium-Ion (Li+) battery. The AP2406 can supply 600mA of load current from a 2.5V to 5.5V input voltage. The output voltage can be regulated as low as 0.6V. The AP2406 can also run at 100% duty cycle for low dropout operation, extending battery life in portable system. Idle mode operation at light loads provides very low output ripple voltage for noise Sensitive applications. The AP2406 is offered in a low profile (1mm) 5-pin, thin SOT package, and is available in an adjustable version and fixed output voltage of 1.2V, 1.5V and 1.8V

High-Speed, Low-Power Dual Operational Amplifier The AD826 features high output current drive capability of 50 mA min per amp, and is able to drive unlimited capacitive loads. With a low power supply current of 15 mA max for both amplifiers, the AD826 is a true general purpose operational amplifier. The AD826 is ideal for power Sensitive applications such as video cameras and portable instrumentation. The AD826 can operate from a single +5 V supply, while still achieving 25 MHz of band width. Furthermore the AD826 is fully specified from a single +5 V to ±15 V power supplies. The AD826 excels as an ADC/DAC buffer or active filter in data acquisition systems and achieves a settling time of 70 ns to 0.01%, with a low input offset voltage of 2 mV max. The AD826 is available in small 8-lead plastic mini-DIP and SO packages.

PRODUCT DESCRIPTION The AD810 is a composite and HDTV compatible, current feedback, video operational amplifier, ideal for use in systems such as multimedia, digital tape recorders and video cameras. The 0.1 dB flatness specification at bandwidth of 30 MHz (G = +2) and the differential gain and phase of 0.02% and 0.04° (NTSC) make the AD810 ideal for any broadcast quality video system. All these specifications are under load conditions of 150 ? (one 75 ? back terminated cable). The AD810 is ideal for power Sensitive applications such as video cameras, offering a low power supply current of 8.0 mA max. The disable feature reduces the power supply current to only 2.1 mA, while the amplifier is not in use, to conserve power. Furthermore the AD810 is specified over a power supply range of ±5 V to ±15 V.
