1. A level-conversion circuit, comprising:
a PMOS-driver control unit;
an NMOS-driver control unit;
a PMOS-side power-source control unit;
an NMOS-side power-source control unit;
an output unit; and
an output-feedback unit that outputs an inverted output signal, wherein,
each of the PMOS-driver control unit and the NMOS-driver control unit inverts a small-amplitude input signal and transmits the inverted small-amplitude input signal to the output unit, and
each of the PMOS-side power-source control unit and the NMOS-side power-source control unit establishes electrical continuity between the output unit and at least one power source upon receiving the inverted output signal so that the output unit transmits a large-amplitude output signal.
