基极耦合逻辑(BCL)是一种新型逻辑线路结构。它由基极耦合电流开关和跟随器组成,用于超高速数字通信系统。由于比射极耦合逻辑(ECL)使用较低的电源电压,故功耗减少。由于“与”“或”和“非”的功能是直接执行而不经转换,使逻辑设计减化了。线路采用的是薄膜工艺,BCL门的级延迟和上升下降边沿的典型值是300Ps, The base coupling logic (BCL) is a new type of logic structure. It consists of a base-coupled current switch and follower for ultra-high-speed digital communication systems. Power consumption is reduced due to the lower supply voltage than emitter-coupled logic (ECL). Since the “AND” or “AND” functions are executed directly without conversion, the logic design is reduced. Line is thin film technology, BCL gate level delay and rising and falling edge of the typical value is 300Ps,
