一、引言集成注入逻辑(I~2L)于1972年问世,至今,在国际上它已经被公认为实现双极大规模集成电路的重要技术途径,被誉为半导体大规模、超大规模集成电路的五大技术之一。集成注入逻辑之所以引起人们那么大的兴趣,是因为它有一般双极型电路,甚至MOS 型电路所不具备的一些优点,例如,它可以有较高的集成度,较低的功耗—延迟时间乘积,以及可以与其他双极型电路相容等。上述优点恰好是大规模集成电路所要求的。不仅如此,集成注入逻辑应用领域也很广,仪表、电讯、自动控制、电子计算机、以及电视接收机等都应用了注入逻辑电路。在国际上,已经研制成功16位单片I~2L 微处理机和16k 的动态随机存贮器。我国科技工作者和工人,发扬了自力更生奋发图强的革命精神,于今年初,研制成功第一台注入逻辑微处理机。第一代经典注入逻辑的主要缺点是开关速度较慢,一般门延迟时间在40～100ns。这
I. INTRODUCTION INTEGRATED INJECTION LOGIC (I ~ 2L) came out in 1972. So far, it has been recognized as an important technical way to realize bipolar LSI in the world. It is known as a large-scale semiconductor and a very large-scale integrated circuit One of the five technologies. The reason that integrated injection logic draws so much interest is that it has some advantages that typical bipolar and even MOS-type circuits do not have, such as higher integration and lower power consumption - Delay time product, and can be compatible with other bipolar circuit. The above advantages happen to be required by large scale integrated circuits. Not only that, integrated injection logic is also widely used in applications, instrumentation, telecommunications, automation, computer, and television receivers are applied to the injection logic. In the world, has successfully developed 16-bit single-chip I ~ 2L microprocessor and 16k of dynamic random access memory. Our scientific and technological workers and workers carried forward the revolutionary spirit of self-reliance, active development and vigorous development. At the beginning of this year, we successfully developed the first injection logic microprocessor. The first generation of classic logic into the main drawback is the slow switching speed, the general door delay time 40 ~ 100ns. This
