引言晶体管与隧道二极管的组合提供了充分利用每种器件最大的优点来实现高速计算机线路的可能性。当这些器件互相取长补短时,就能够获得很好的性能.而单靠一种器件要获得这些性能就必然极为复杂或提出非常高的容差要求。在高速开关应用中.为了电流增盆而采用晶体管时,不管晶体管以何种方式工作,都将不可避冤地减慢线路的工作速度。共基极线路没有电流增益的能力,因而是最快的一种工作 Introduction The combination of a transistor and a tunnel diode offers the potential to take full advantage of the maximum benefits of each device for high-speed computer wiring. When these devices complement each other to get good performance, and rely on a device to obtain these properties must be extremely complex or very high tolerance requirements. In high-speed switching applications, transistors are used to increase the current, regardless of the way the transistor works, which inevitably slows down the line. The common base line has no current gain capability and is therefore the fastest type of work
