论文首先介绍了SRAM型FPGA的典型代表XC4000系列的结构和主要特性，并对XC4000系列器件的配置模式和配置顺序做了简单介绍。根据XC4000系列器件各组成模块的功能和特点，可以将其分为可编程逻辑功能块(CLB)、输入输出功能块(IOB)、互连资源(IR)、可配置接口模块(CIM)和进位逻辑(CLM)等五大部分组成。 对于这五个功能模块，可以采用“分治法”分别考虑各个模块的测试问题。论文随后深入讨论了各模块的测试问题，由于RAM测试的特殊性，所以对函数发生器RAM模式的测试单独进行了讨论。

Abstract: IC switches and multiplexers are proliferating, thanks to near-continual progress in lowering the supply voltage,incorporating fault-protected inputs, clamping the output voltage, and reducing the switch resistances. The latest of these advancesis the inclusion of precision resistors to allow two-point calibration of gain and offset in precision data-acquisition systems.

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).

Sensors for pressure, load, temperature, acceleration andmany other physical quantities often take the form of aWheatstone bridge. These sensors can be extremely linearand stable over time and temperature. However, mostthings in nature are only linear if you don’t bend them toomuch. In the case of a load cell, Hooke’s law states that thestrain in a material is proportional to the applied stress—as long as the stress is nowhere near the material’s yieldpoint (the “point of no return” where the material ispermanently deformed).

IR2110是IR公司的桥式驱动集成电路芯片，它采用高度集成的电平转换技术，大大简化了逻辑电路对功率器件的控制要求，同时提高了驱动电路的可靠性[1]。对于我设计的含有ZCS环节的单相光伏逆变电路中有6个IGBT，只需要3片芯片即可驱动，通过dsp2812控制实现软开关和逆变的功能，同时只需要提供3.3 V，12 V的基准电压即可工作，在工程上大大减少了控制变压器体积和电源数目，降低了产品成本，提高了系统可靠性。

Abstract: Rail splitting is creating an artificial virtual ground as a reference voltage. It is used to set the signalto match the op amp's "sweet spot." An op amp has the most linear- and distortion-free qualities at that sweetspot. Typically, the sweet spot occurs near the center between the single power rail and ground. In the case ofa number of signals, the virtual ground can control channel DC errors when multiplexing or switching thesignals.

Video cable driver amplifi er output stages traditionallyrequire a supply voltage of at least 6V in order to providethe required output swing. This requirement is usuallymet with 5V supplies by adding a boost regulator or asmall local negative rail, say via the popular LT®1983-3.Such additional circuitry is unnecessary in typical 1VP-Pvideo connections, such as HD component video, if thecable driver amplifi ers simply offer near rail-to-rail outputcapability when powered from 5V.

This ink marks LTC’s eighth circuit collection publication.1We are continually surprised, to the point of near mystification, by these circuit amalgams seemingly limitlessappeal. Reader requests ascend rapidly upon publication,remaining high for years, even decades. All LTC circuitcollections, despite diverse content, share this popularity,although just why remains an open question. Why isit? Perhaps the form; compact, complete, succinct andinsular. Perhaps the freedom of selection without commitment,akin to window shopping.
