<p>The purpose of the present invention is to provide a circuit that generates a reference voltage with little electrical power consumption, and that has the similar as conventional circuits. A bandgap reference circuit that, to generate an output voltage, adds a voltage proportional to a differential voltage when currents having different current densities are applied to a semiconductor junction, and a voltage proportional to a forward voltage occurring in a semiconductor junction, wherein the bandgap reference circuit is characterized in that the“voltage proportional to the differential voltage”is generated by a first tunneling current element to which the differential voltage is applied, circuits connected to a second tunneling current element or a serial circuit of second tunneling current elements, and a means to apply, to the second tunneling current element, a current proportional to the current applied to the first tunneling current element.</p> |
