論文首先介紹了SRAM型FPGA的典型代表XC4000系列的結構和主要特性，并對XC4000系列器件的配置模式和配置順序做了簡單介紹。根據XC4000系列器件各組成模塊的功能和特點，可以將其分為可編程邏輯功能塊(CLB)、輸入輸出功能塊(IOB)、互連資源(IR)、可配置接口模塊(CIM)和進位邏輯(CLM)等五大部分組成。 對于這五個功能模塊，可以采用“分治法”分別考慮各個模塊的測試問題。論文隨后深入討論了各模塊的測試問題，由于RAM測試的特殊性，所以對函數發生器RAM模式的測試單獨進行了討論。

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公司的橋式驅動集成電路芯片，它采用高度集成的電平轉換技術，大大簡化了邏輯電路對功率器件的控制要求，同時提高了驅動電路的可靠性[1]。對于我設計的含有ZCS環節的單相光伏逆變電路中有6個IGBT，只需要3片芯片即可驅動，通過dsp2812控制實現軟開關和逆變的功能，同時只需要提供3.3 V，12 V的基準電壓即可工作，在工程上大大減少了控制變壓器體積和電源數目，降低了產品成本，提高了系統可靠性。

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.
