A semiconductor integrated circuit comprises first and second transistors, and a resistive element. The first transistor includes first and second regions of first conductivity type in a first well region of opposite conductivity type, and a first gate electrode on the first well region between the first and second regions. The second transistor includes third and fourth region of second conductivity type in a second well region of opposite conductivity type, and a second gate electrode on the second well region between the third and fourth regions. The first region is connected to a first line, and the third and fourth regions are connected to a second line. The resistance element includes a first end connected to the first and second gate electrodes, a second end connected to the second line, and a resistive electrical path between the first and second ends including a portion of the third region.
