提出了一种新型逻辑电路——三层结构逻辑(3JL)。3JL由一种新型NPNM四极管构成,只有三层半导体区,制作工艺简单。其速度、功耗和集成密度均优于I~2L。可与I~2L相容。采用普通工艺已研制出四位加法器等部件,所研制的闭环振荡器,最快速度为5ns,最低功耗延迟积为0.55pJ。集成密度可达200～800门/mm~2。对双极大规模集成和微处理机。3JL是一种很好的逻辑电路形式。本文简述了NPNM四极管的工作原理,讨论了3JL的抢电流效应、负载能力以及高速低功耗特点,给出了逻辑构成、接口形式,以及研制结果。
A new type of logic circuit is proposed - three-layer structure logic (3JL). 3JL by a new NPNM tetrode, only three layers of semiconductor area, the production process is simple. Its speed, power consumption and integrated density are better than I ~ 2L. Compatible with I ~ 2L. Using common technology has developed four adders and other components, developed by the closed-loop oscillator, the fastest speed of 5ns, the minimum power delay product is 0.55pJ. Integrated density up to 200 ~ 800 / mm ~ 2. Large-scale integration of bipolar and microprocessors. 3JL is a good form of logic. In this paper, the working principle of NPNM diode is briefly introduced. The current jamming, load capacity and high speed and low power consumption of 3JL are discussed. The logic constitution, interface form and the result of development are given.
