<P>PROBLEM TO BE SOLVED: To provide a reference voltage generation circuit that can sufficiently improve temperature characteristics of reference voltage by simple adjustment using a small scale additional circuit. <P>SOLUTION: The reference voltage generation circuit comprises: a bipolar transistor 106; a bipolar transistor 107 connected in parallel with a bipolar transistor 106; a resistance element 104 having one end connected to an emitter of the bipolar transistor 107; a resistance element 109 that generates difference voltage caused by a difference between a base potential of the bipolar transistor 106 and a base potential of the bipolar transistor 107; a computing amplifier 105 that operates so as to equalize an emitter potential of the bipolar transistor 106 and a potential of the other end of the resistance element 104. The difference voltage generated by the resistance element 109 changes with temperature. <P>COPYRIGHT: (C)2013,JPO&INPIT |
