Integrated circuits for large-scale transistor tensor operations

An integrated circuit comprising:

• a plurality of current-mode computation (CMC) branches, wherein each of the CMC branches comprises:
• a plurality of CMC cells, wherein each of the CMC cells comprises at least one computation transistor and produces a CMC cell output current that is a function of a channel current of the computation transistor;
• a branch summation line comprising an electrical conductor that is electrically coupled to, and receives the CMC cell output currents produced by, a plurality of the CMC cells in that individual CMC branch, and that produces a branch output current that is a current-mode summation of the CMC cell output currents electrically coupled thereto;
• a plurality of layer-one current summation circuits, wherein each of the layer-one current summation circuits is electrically coupled to, and receives the branch output current produced by, at least one branch summation line, and further comprises a feedback circuit that can limit at least an amplitude of the branch output current received thereto, and produces a layer-one current summation circuit output current that is a function of the branch output currents received thereto;
• a plurality of layer-two summation lines, wherein each of the layer-two summation lines comprises an electrical conductor that is electrically coupled to, and receives the layer-one current summation circuit output currents produced by, a plurality of layer-one current summation circuits, and that produces a layer-two summation line output current that is a current-mode summation of the received layer-one current summation circuit output currents;
