CURRENT SOURCE ARRANGEMENT FOR THREE-LEVEL EMITTER-COUPLED LOGIC AND FOUR-LEVEL CURRENT MODE LOGIC.

摘要

the emitter coupled logic to three or four level logic cml is feasible when a power source of low voltage drop (34) is embedded in the mounting portare in series. the power source with a low voltage drop (34) is less than one tenth of the difference between the voltage vcc and the earth.a large part of the difference between the voltage vcc and the earth, up to 4 volts, is reserved for the three levels of logic to the coupling by the issuer or the four levels of logic cml.conventional power supplies are used, despite the increase in the number of logic functions.
