The multifunctional current logical element for digital computing devices, operating on the principles of linear (not boolean) algebra

Abstract

In the article the task of construction of the multifunctional current logical element (MLE), which realizes the analogues of logical functions of the Boolean main functionally complete system (AND, OR, NOT), and also the comparison operation x₁>x₂ is solved for the first time. The quantum of the current I₀ is an equivalent of the standard logical signal here. The suggested MLE also provides the normalization of the signal levels - the generation of the output current, which is equal to I0, without regard to the spread (up to 0.5I₀) of numerical values of the input current logical variables. The concrete logical function, performed by MLE, is determined by the level of the reference DC current I₁ (I₁=0.5I₀, I₁=I₀, I₁=1.5I₀), which is applied to the low-ohmic current input of MLE.
