TWO-INPUT "AND" LOGIC GATE WITH MULTIDIGIT INTERNAL SIGNAL PRESENTATION Russian patent published in 2014 - IPC H03K19/00 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to computer engineering and automation, and can be used in different automatic control, information transmission systems etc. The two-input AND logic gate with multidigit internal signal presentation includes first (1) and second (2) input current quanta I₀ switches which are controlled by input logic voltage sources (3) and (4), a current-stabilising two-terminal element (5) connected between combined current outputs (6), (7) of the first (1) and second (2) input current quanta I₀ switches and the power supply bus (8). Current outputs (6), (7) of the first (1) and second (2) input current quanta I₀ switches are connected to the emitter of an additional transistor (9), the base of which is connected to a reference voltage source (10) and the collector is the logic current output of the device (11), wherein the current-stabilising two-terminal element (5) used is a reference current source whose output current is a multiple of the current quanta I₀.

EFFECT: high speed of operation and creating an element base for computing devices operating on multidigit linear algebra principles.
