电流导引技术自59年发表电流开关电流导引技术之后,到67年在集成电路中采用该技术设计了一系列电路。在分离元件的条件下实现电流导引技术,需要用较多的元件来解决各层间的电平转换问题,以使线路工作在非饱和状态,然而这样作虽然速度很快可是线路的标准化增加了困难。这个问题在集成电路中比较容易解决。这样发挥了电流导引技术逻辑功能强、所耗费的功率小的特点,并保持了高速运行。电流导引技术和水在水管中流动是很相似的,线路结构象一棵树,有好几层,层数越多则功能越复杂。ECL 的讯号幅度为800毫伏时,利用三极管或二极管都可以得到完整的电平转换,层与层之问的控制电平转换容易,利于线路标准化。层数多则讯号电平转的次数也多,电源电压的最小值随层数增加而增加。电
Current steering technology Since the publication of current switching current steering technology in 59, a series of circuits have been designed using this technology in integrated circuits by 67 years. Implementing the current steering technique with separate components requires more components to solve the problem of level shifting between the layers to make the line work in a non-saturating state, yet this is done at a faster rate but with a more standardized line Difficulties. This problem is easier to solve in integrated circuits. This gives play to the logic-intensive current-steering technology that consumes less power and maintains high-speed operation. Current steering technology and water flow in the water pipe is very similar, the line structure like a tree, there are several layers, more layers, the more complex functions. ECL signal amplitude of 800 millivolts, the use of transistors or diodes can be a complete level conversion, layer and layer control of the level of conversion between the easy, which will help standardize the line. The number of layers is more than the number of signal levels, the minimum supply voltage increases with the number of layers. Electricity
