[/en][cn]5.發(fā)明了半導(dǎo)體器件后,真空二極管的使用呈迅速下降趨勢,因為半導(dǎo)體器件具有真空管的許多功能.

用以實現(xiàn)任何設(shè)計的通用微處理器的話，電子行業(yè)就不會競爭得如此激烈了。[/cn] [en]6.One way of creating fusion here on earth is to heat and compress pellets containing hydrogen to the temperatures and pressures needed to fuse the nuclei

[en]1.The commercial success of the integrated circuit industry was based on standard products representing digital logic families.[/en][cn]1.集成電路工業(yè)的商業(yè)成就是在以數(shù)字邏輯家族為代表的標(biāo)準(zhǔn)產(chǎn)品的基礎(chǔ)上取得成功的。[/cn] [en]2.This curriculum includes the elementary theory of passive component (resistor,capacitor and inductor

要被設(shè)計（當(dāng)然，盡管要用到一些庫）。[/cn] [en]2.For many years, however, it has been possible to build semi-custom integrated circuits using gate arrays. A gate array, as its name suggests, is an integrated circuit on which an array of gates has been created. The design of an application-specific integrated circuit (ASIC) using a gate array therefore involves the definition of how the gates in the array should be connected.[/en][cn]2.但是，多年以來，可以使用門陣列構(gòu)建半導(dǎo)體集成電路。門陣列，正如其名，是由許多邏輯門所構(gòu)建的集成電路。因此，使用門陣列進(jìn)行專用集成電路的設(shè)計包括定義列陣中的邏輯門是如何連接的。[/cn] [en]3.In practical terms, this means that one or two layers of metal interconnect must be designed. Since an integrated circuit requires seven or more processing stages, all the processing steps other than the final metalization can be completed in advance. Because the uncommitted gate arrays can be produced in volume, the cost of each device is relatively small.[/en][cn]3.在實際情況中，這意味著一到兩層的金屬互連必須被設(shè)計。由于集成電路需要七個或更多的加工過程，除了最終的金屬化，其它步驟都可以預(yù)先完成。因為這些未知用途門列陣可以大量生產(chǎn)，每個器件的成本非常低。[/cn] [en]4.A diode is reverse biased when the diode negative electrode voltage is higher than the anode electric potential. The diode internal resistance was extremely high by now.[/en][cn]4.當(dāng)二極管的正極電壓高于負(fù)極電位時稱二極管反向偏置，這時二極管的內(nèi)部電阻非常高，所以一個理想的二極管可以阻擋反向的電流而讓正向的電流通過。[/cn] [en]5.There are four basic tests required for transistors in practical applications: gain, leakage, breakdown, and switching time. All of these tests are best made with commercial testers or oscilloscopes.[/en][cn]5.在實際應(yīng)用中，對晶體管須進(jìn)行四項基本測試：增益、漏電流、擊穿電壓和開關(guān)時間。所有這些測試最好用通用晶體管測試儀和示波器進(jìn)行測試。[/cn]

[en]1.Consider what we know intuitively about an integrator. If you apply a DC signal at the input (i.e. , zero frequency), the output will describe a linear ramp that grows in amplitude until limited by the power supplies. Ignoring that limitation, the response of an integrator at zero frequency is infinite, which means that it has a pole at zero frequency. (A pole exists at any frequency for which the transfer function’s value becomes infinite.)[/en][cn]1.我們怎么從直觀上理解積分器呢？假設(shè)在輸入端加上一個直流信號（頻率為0），那么在輸出端將會出現(xiàn)一個線性斜坡信號,其幅度一直增至電源電壓。如果不考慮電源電壓對輸出信號的限制，積分器在零頻率上的響應(yīng)將是無窮大，這意味著它在零頻率點上存在一個極點（在任何使傳遞函數(shù)為無窮大值的頻率點上都存在一個極點）。[/cn] [en]2.While the complex frequency’s imaginary part helps describe a response to AC signals, the real part helps describe a circuit’s transient response. [/en][cn]2.復(fù)頻率的虛部有助于描述電路對交流信號的響應(yīng)，而其實部有助于描述電路的瞬態(tài)響應(yīng)。[/cn] [en]3.The low-pass filter’s transient response is more stable, because its pole is in the negative-real half of the complex plane.[/en][cn]3.低通濾波器的瞬態(tài)響應(yīng)更加穩(wěn)定，因為其極點位于復(fù)平

收到的信號極其微弱，其電平僅比噪聲稍高一點。[/cn] [en]4.However,for applications in which the end product must process answers in real time,or must do so while powered by consumer batteries,GPPs comparatively poor real time performance and high power consumption all but rules them out.[/en][cn]4.然而，在最終產(chǎn)品必須實時響應(yīng)的應(yīng)用中，或者必

for removal), one or more leads should be disconnected and care taken to avoid current paths in neighboring components when testing.[/en][cn]5.理想的方法是把該元件從線路中完整取出。但如果不方便的話（至少要在判別需要去掉之前），應(yīng)該斷開一根或幾根引線，應(yīng)當(dāng)避免在測試時鄰近的元件之間有電流通路。[/cn]

有時也被稱為可靠性因子。[/cn] [en]3.Why is skew important? In high-speed systems, clock skew forms an important component of timing margin. A skew of 1 ns is a significant portion of a 15-ns cycle time. If the timing budget does not allow for skew, it is highly likely that the system will perform unreliably.[/en][cn]3.為什么偏移這么重要？在高速系統(tǒng)中，時鐘偏移是時序富裕量的重要組成部分。在一個以15納秒為周期的時間里，1納秒的偏移都是很顯著的部分。如果時序預(yù)算不允許偏移，系統(tǒng)很可能無法穩(wěn)定運行。[/cn] [en]4.In today's designs, with clock rates over 100 MHz and rise times commonly 1 nanosecond (ns) or less, designers cannot ignore the role interconnections play in a logic design. [/en][cn]4.在當(dāng)今的設(shè)計中，時鐘速率都超電阻與電源并聯(lián)連接,則電阻限定流入裝置的電流.電過了100MHz，并且上升沿通常只有1納秒或者更少，設(shè)計者不能忽視在邏輯設(shè)計中互連的重要性。[/cn] [en]5.The faster clock rates and rise times increase both capacitive and inductive coupling effects, which makes cross talk problems greater. They also mean shorter time for reflections to decay before the data is clocked and read, which decreases the maximum line length that can be used for unterminated systems.[/en][cn]5.更快的時鐘速率和上升沿都將增加電容耦合及電感耦合效應(yīng)，這使得串?dāng)_問題更加嚴(yán)重。這也意味著在數(shù)據(jù)被寫入和讀取之前的反射衰減時間更短，它減少了無終端系統(tǒng)中最大的可用線路長度。[/cn]

一是確保高速脈沖通過整個互連路徑時的信號完整性，從器件到PCB板，再從PCB板到底板，最后到任何可能出現(xiàn)的網(wǎng)絡(luò)連接。[/cn] [en]4.This is Ohm’s law and can be expressed as the formula:I=U/R . The resistor is generally a linear device and its characteristic forms a straight line when plotted on a graph.[/en][cn]4.這就是歐姆定律,可以用公式表示成I=U/R.電阻器一般是線性器件,它的(伏安)特性曲線形成一條直線.[/cn] [en]5.One Ohm is defined as that amount of resistance that will limit the current in a conductor to one ampere when the voltage applied to the conductor is one volt.[/en][cn]5.1Ω的定義是當(dāng)加到導(dǎo)體上的電壓為1V時,使導(dǎo)體的電流為1A時所需要的電阻值.[/cn]
