Claim Text:
1. A band-gap reference voltage circuit comprising: an operational amplifier; a first diode having an anode and a cathode, the anode being electrically connected to a non-inverting input terminal of the operational amplifier and the cathode being grounded; a first resistor having one end electrically connected to an output terminal of the operational amplifier and another end electrically connected to the anode of the first diode; a second resistor having one end electrically connected to the output terminal of the operational amplifier and another end electrically connected to an inverting input terminal of the operational amplifier; a third resistor having one end electrically connected to the inverting input terminal of the operational amplifier; and a second diode having an anode and a cathode, the anode being electrically connected to another end of the third resistor and the cathode being grounded; wherein one end of a first wiring line is configured to electrically connect the non-inverting input terminal of the operational amplifier to the anode of the first diode, and one end of a second wiring line is configured to electrically connect the first resistor to the anode of the first diode, said one end of the first wiring line and said one end of the second wiring line both being connected to a connection terminal of the first diode stacked on the anode of the first diode, and wherein a band-gap reference voltage is output from the output terminal of the operational amplifier.
