<p>A current-based logic cell comprises input means (13, 14), output means (12, 21-24) and processing means (10) coupled to the input and output means. The input means includes an input wire arranged for direct application of a plurality of input signals thereto, each input signal being a current. The processing means is responsive to an algebraic summation of currents flowing in one direction in said input wire to control development at the output means or of first or second forms of output signals.</p> |
