前言想要使LSI的输入输出规格、各种特性、封装条件同商品集成电路(例如ECL电路)之间具有兼容性并重视其通用性与经济性时,LSI内部逻辑电平的划分问题就显得重要起来。 LSI里存在的问题与解决办法因为要求LSI输出规格具有兼容性,所以实现LSI输出门低功耗化是个极其困难的问题。此外,由于冷却条件也要求相容,所以LSI的总功耗就要降低,结果分配到内部门电路的功耗就非常少。在这样困难的条件下,仍 INTRODUCTION In order to make LSI's input and output specifications, various characteristics, and package conditions compatible with commercial ICs (such as ECL circuits) and to emphasize its versatility and economy, the problem of dividing the internal logic levels in LSIs appears Important up Problems and Solutions in LSI Because LSI output specifications are required to be compatible, it is extremely difficult to reduce the power consumption of the LSI output gate. In addition, since the cooling conditions are also required to be compatible, the total power consumption of the LSI is reduced, and as a result, the power dissipated in the internal gate is very small. In such difficult conditions, still
