Title: Reference voltage generating circuit
Inventor: NAKADE TOSHIMITSU
IPC: H01L21/822
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a reference voltage generating circuit which can very accurately control the temperature dependence. SOLUTION: In a reference voltage generating circuit 31, a voltage which is x times as high as a voltage difference between an inter-base/emitter voltage of a positive temperature coefficient transistor 33 and that of a transistor 34 is applied to a transistor 35 so as to cancel a voltage change in an inter-base/ emitter voltage of negative temperature coefficient. The above voltage change with a temperature change can not be completely eliminated because the bipolar transistors 33 to 35 vary in characteristics, but the inter-base/emitter voltage of the transistor 33 is controlled by a current output circuit 41, whereby the reference voltage generating circuit 31 is controlled in voltage change caused by a temperature change in transistors.
