1. A current mode logic circuit comprising:

  • a first NMOS transistor and a second NMOS transistor;

    a data input terminal connected to a gate of the first NMOS transistor to which data is inputted;

    a reference voltage input terminal connected to a gate of the second NMOS transistor to which a reference voltage is supplied;

    an output terminal connected to a drain of the first NMOS transistor or the second NMOS transistor; and

    a constant current source connected to both of sources of the first NMOS transistor and the second NMOS transistor,wherein a body terminal of the fist NMOS transistor is connected to the data input terminal and a body terminal of the second NMOS transistor is connected to the reference voltage input terminal so that a level of a body voltage of each of the first NMOS transistor and the second NMOS transistor is controlled.
