本文论述了用集成注入逻辑(I~2L)技术制造可编程序逻辑阵列(PLA)的某些考虑。这些考虑以I~2L特有的实验数据为基础,并在三种不同编码的10—16—14PLA的制造中证实了其合理性。电流匹配对于这种包括多达16个集电极的I~2L电路尤其重要。从典型的工艺结构出发,提出的设计方案,使上述问题得到满意的解决。 This article discusses some considerations for fabricating a programmable logic array (PLA) using integrated injection logic (I ~ 2L) technology. These considerations are based on I ~ 2L specific experimental data and justified in the manufacture of three different coded 10-16-14 PLA. Current matching is especially important for this type of I ~ 2L circuit that includes up to 16 collectors. Proceeding from the typical structure of the technology, the proposed design scheme has solved the above problems satisfactorily.
