Title:
TUNNELING CURRENT CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2012/172927
Kind Code:
A1
Abstract:
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 same size 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 serially to a second tunneling current element or a plurality 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.
