Abstract:
A voltage generating circuit, in which the influence of offset of an amplifier on an output voltage is reduced, has first and second bipolar transistors (Q 1 , Q 2 ) having emitter terminals at the same electric potential. A base terminal of Q 1  is disposed on a collector side of Q 2 . A first resistance element connects the collector side of Q 2  with the base side of Q 2 ; and a second resistance element (R 1 ) connects a collector side of Q 1  to R 2 . A third resistance element (R 3 ) connects a base terminal of Q 2  with the electric potential of the emitter terminals. An amplifier (A 1 ) outputs a voltage based on a voltage difference between the collector sides of Q 1  and Q 2 ; and a voltage-current converting section (MP 1 , MP 2 ) converts amplifier output into a current supplied to the connection node of R 1  and R 2 . A voltage is then output on the basis of the generated current.

Claim (Index 1):
A voltage generating circuit comprising:\n a current generating section that generates a current obtained by adding a current based on a voltage difference between base-emitter voltages of two bipolar transistors having different emitter areas and a current based on a forward voltage of a PN junction, and an output section that converts an input current into a voltage and outputs the converted voltage, wherein the current generating section includes a first bipolar transistor that includes an emitter terminal disposed on a first electric potential node side; a second bipolar transistor that has an emitter area larger than an emitter area of the first bipolar transistor, includes an emitter terminal at the same electric potential as in the emitter terminal of the first bipolar transistor and includes a base terminal disposed on a collector side of the first bipolar transistor; a first resistance element that is disposed on the collector side of the first bipolar transistor at one end thereof and is disposed on a base side of the first bipolar transistor at the other end thereof; a second resistance element that is disposed on a collector side of the second bipolar transistor at one end thereof and is connected to the other end of the first resistance element at the other end thereof; a third resistance element that is provided between a base terminal of the first bipolar transistor and the first electric potential node; an amplifier that receives, as inputs, a voltage on the collector side of the first bipolar transistor and a voltage on the collector side of the second bipolar transistor and outputs a voltage based on a voltage difference between two input voltages; and a voltage-current converting section that receives, as an input, the output voltage of the amplifier, converts the received voltage into a current and supplies the converted current to a connection node of the first resistance element and the second resistance element and to the output section, wherein the current supply to the connection node of the first resistance element and the second resistance element from the voltage-current converting section is performed through a resistance element.
