前言随着电子计算机与数据处理技术日趋复杂,对数字集成电路的速度提出了更高的要求。近十年来,集成电路的制造技术在不断改进,平均延迟时间已经从原来的10~2毫微秒减小到1毫微秒以内,几乎提高了二个数量级。最近正在进行亚毫微秒电路的研制,但困难还很多。在亚毫微秒电路中,晶体管的截止频率f_T 必须达到5～7千兆赫,为了实现这样高的截止频率,要求元件隔离时所产生的寄生 Preface With the increasingly complex electronic computer and data processing technology, put forward higher requirements for the speed of digital integrated circuits. In the past decade, the manufacturing technology of integrated circuits has been continuously improved. The average delay time has been reduced from 10 to 2 nanoseconds to less than 1 nanosecond, which has increased by almost two orders of magnitude. Recent sub-nanosecond circuit development, but the difficulties are still many. In the sub-nanosecond circuit, the transistor cut-off frequency f_T must reach 5 to 7 GHz, in order to achieve such a high cut-off frequency, the components required to produce parasitic parasitic
