CIRCUIT FOR PRODUCING LOGIC ELEMENTS REPRESENTABLE BY THRESHOLD EQUATIONS

摘要

The invention relates to a circuit by means of which all logic elements which can be represented in the form of a threshold equation can be produced. To this end, parallel transistors (T1, T2, T3, ..., Tn) of a transistor unit are dimensioned so that the transverse currents (It1, It2, It3, ..., Itn) flowing through the transistors (T1, T2, T3, ..., Tn) represents a weighted summand of a first term of the threshold equation. A second term in the threshold equation is formed by a reference current IR representing the value of the second term. An evaluation unit (BE) compares a total current found from the sum of the transverse currents (It1, It2, It3, ..., Itn with the reference current IR. The result of evaluation is provided in the form of a stable output signal at an output of the evaluation unit (BE).
