Semiconductor large scale integrated circuit chip having current switching type logical circuits

摘要

A semiconductor large scale integrated circuit chip is characterized in that current switching type logical circuits are arranged at the central part of the chip, each of the logical circuits having a current source which is so constructed as to be capable of changing its current value through a change in its connection. Emitter-follower transistors are arranged at the peripheral part of the chip, each of the emitter-follower transistors receiving the output of the current switching type logical circuit as its base input, and a resistor as a load resistor of the current switching type logical circuit is connected to the base of the transistor.
