Abstract:
A semiconductor integrated circuit device comprising:a first transistor of a first conductivity type having a source for receiving a first potential; a second transistor of the first conductivity type having a source for receiving the first potential, a gate connected to a drain of said first transistor, and a drain connected to a gate of said first transistor; and a third transistor of a second conductivity type having a drain for receiving a potential from the drain of said first transistor, a gate for receiving a first signal, and a source for receiving a second signal, wherein a threshold voltage of the third transistor is set to about 0V, wherein the first potential is positive to a potential of the first signal when the first signal is in a high level, the first conductivity type is p type, and the second conductivity type is n type, and wherein said third transistor is weakly or strongly inverted when a low-level potential of the first signal is applied to the gate, the source, and a substrate, and the first potential is input to the drain.
