PROBLEM TO BE SOLVED: To provide a constant current source that is not restrained by a manufacturing process therefor, not affected by a variation in the threshold value of an MOS transistor and the temperature dependence, and can be jointly used with an ED type standard voltage source, and an amplifier circuit and a constant voltage circuit using the constant current source.;SOLUTION: A correction is made to an output current of the constant current source 1 in which a deviation of a monitoring current i1 supplied from a monitoring current source 2 is checked accurately, the amount of the deviation is outputted to each of constant current circuits A1-An as a digital signal, a current value i2 proportional to the monitoring current i1 is supplied, and a standard current source 25 in the constant current circuits A1-An is used as a standard current, The constant current source 1 is used in a constant voltage circuit equipped with an amplifier circuit and an error amplifier circuit.;COPYRIGHT: (C)2006,JPO&NCIPI
