LOGIC ELEMENT FOR EQUALITY COMPARISON OF TWO MULTI-VALUE VARIABLES Russian patent published in 2015 - IPC H03K19/00 

FIELD: information technology.

SUBSTANCE: logic element for equality comparison of two multi-value variables includes first and second device current inputs and a device current output; first and second output transistors with integrated bases, which are connected to a first bias voltage source; third and fourth output transistors of another conductivity type with integrated bases, which are connected to a second bias voltage source; the emitters of the first and third output transistors are integrated and connected to the first device current input, and the emitters of the second and fourth output transistors are connected to each other; a first reference current source, a first current mirror interfaced with a first power supply bus, a second mirror interfaced with the first power supply bus.

EFFECT: designing a logic element for equality comparison of two multi-value variables, wherein internal information conversion is carried out in a multi-value current form of signals.
