ABSTRACT:
A power supply circuit is disclosed in which the influence due to variation in the characteristics of transistors is reduced by variation alleviating devices, each connected to transistors that constitute a current mirror. The power supply circuit comprises a configuration having a current mirror to produce a reference voltage. A multiple number of transistors constitute a current mirror. Multiple variation alleviating devices are connected in series with individual transistors.
