Abstract:
A current mirror circuit, which has a plurality of output transistors serving as current mirror outputs, comprising:a first input transistor whose one end is connected to a first constant current source and whose another end is connected to a first connecting position at a first potential, which is used as an input side of a current mirror; a second input transistor whose one end is connected to a second constant current source, which is disposed with being separated from said first input transistor by a predetermined distance and is used as an input side of a current mirror; a first feeder line which connects said other end of said first input transistor with another end of said second input transistor; a first potential line which connects said one end of said first input transistor with said one end of said second input transistor with a resistance that is higher than a resistance of said first feeder line, to produce a potential gradient; and a plurality of output transistors distributed between said first input transistor and said second input transistor, which are coupled to said first feeder line and said first potential line and are used as an output side of a current mirror.
