Emitter coupled logic-bipolar complementary metal oxide semiconductor / complementary metal oxide semiconductor translators

摘要

An ECL-BiCMOS / CMOS translator is disclosed that converts a pair of differential ECL level signals to BiCMOS / CMOS level signals. The translator includes an output node having an output node and having first output switching means for coupling the output node to a first voltage supply and second output switching means for coupling the output node to a second voltage supply, do. The first input terminal activates the first output switching means of the output stage in response to one ECL signal of the differential ECL signal and the second input terminal activates the second output switching means of the output stage in response to the other differential ECL signal. Wherein the first input stage comprises first input switching means for connecting a first resistive element between the first voltage supply source and the output node of the output stage and the second input stage is connected to the first voltage supply source and the second voltage supply source, And second input switching means for connecting a second resistance element between the first and second resistive elements.
