CONSTITUTION: A low-power reversible logic circuit which employs only nMOS transistors includes a clock generator(100) for frequency-dividing a reference clock to generate a plurality of periodic clocks having a phase difference among them, and a reversible logic block(200) having a plurality of reversible logic parts(210,220,230) connected in a pipeline to apply a predetermined number of neighboring clocks among the clocks to the plural reversible logic parts, to thereby reversibly logically operate an input signal(Xi).
