Fast logic operator with high fan-in and complex logic function, using at least two low-threshold field effect transistors

摘要

the invention relates to this achievement, integrated circuit, logical operators rapid, using field effect transistors of low threshold voltage, the so-called "quasi normally blocked.o ensure a wide entrance logic functions more or less complex.;the operator is thus achieved, with the aid of a single logic gate functions very fast, "or otherwise".by using a part of a saturable resistive load input (cs1 and cs11) in series with a pair of transistors of the type referred to above (t 1, t 1) with two gates each have a maximum of.the drain is connected to the gate of a transistor out of the same type (t and t (2).the two portions are mounted in parallel identical circuit half a branch output diode (d) in series with a load dependent (cs2).;application of the logic transistor of gallium arsenide field effect.
