UNIVERSAL BRIDGE INVERTING ADDER Russian patent published in 2008 - IPC G06G7/14 H03K19/20 

FIELD: physics; measurements.

SUBSTANCE: universal bridge inverting adder is designed for use in analogue as well as in digital electronics and computer technology. The universal bridge inverting adder consists of input electrodes connected to positive and negative power supply bus leads of the universal bridge inverting adder corresponding to the first (1) and the second (2) current mirrors. Current mirror (2) is complementary to current mirror (1), and the output complementary transistors (T) (5-8), which are serially connected between the universal bridge inverting adder positive and negative power supply bus leads. Connection points of T (7,8) and T (5,6) are connected to preliminary outputs (14,13) of the universal bridge inverting adder. Between current mirror (1) and current mirror (2) there is a third (3) and fourth (4) current mirror, complementary to current mirror (1) and current mirror (2) respectively. Connection points of the corresponding input electrodes of current mirror (3) and current mirror (4) are connected to the corresponding inputs of the universal bridge inverting adder, and the connection points of the corresponding output electrodes corresponding to current mirror (1, 3) and current mirror (2, 4) are connected to the control electrodes of the output complementary transistors T (5-6) respectively. Each current mirror has the same number of input and output electrodes. Between corresponding output electrodes of current mirrors and the preliminary outputs of the universal bridge inverting adder there are resistors (24, 25), and the preliminary output are joined to the general output of the universal bridge inverting adder through resistors (27, 28).

EFFECT: making of a universal bridge inverting adder with artificial intelligence elements.
