Abstract
A logic gate circuit includes a resistor, a current limiting circuit, a switching transistor, and a load transistor, the source of load transistor being connected to the drain of the switching transistor, the gate of the switching transistor being connected to an input terminal, the resistor being connected between the source of and the gate of the load transistor, and the current limiting circuit being connected between the gate of the load transistor and the source of the switching transistor. By using this logic gate circuit in the low speed operating section of an LSI, the dissipation current and the chip area of the LSI can be reduced even when the gate width and the threshold voltage of the load FET are the same as those in the high speed operating section.
