ABSTRACT:
In order to prevent interference of signals in a plurality of outputs from a current mirror circuit, the current mirror circuit comprises a current mirror input transistor Q1through which a constant current flows and a plurality of current mirror output transistors Q7and Q8which have control ends commonly connected to a control end of the current mirror input transistor Q1. The constant current is supplied from the plurality of current mirror output transistors Q7and Q8to a plurality of operating circuits. Further, at least one of the plurality of current mirror output transistors Q7and Q8is equipped with a low pass filter for removing a high-frequency component contained in a current output from the at least one of the plurality of current mirror output transistors Q7and Q8.
