Pair of bipolar transistor complementary current sources with base current compensation

The present invention relates to electronics, and more particularly, to a pair of complementary current sources. A pair of complementary current sources includes a reference current source, and two complementary current mirrors having the same number of branches provided with bipolar mirror transistors. The bases of the mirror transistors of the complementary mirrors are connected to a common node. One of the complementary mirrors is connected to the reference source. An intermediate current mirror includes a first slave branch connected to the other complementary current mirror, a second slave branch connected to the reference source, and a master branch connected to the output of a trimming circuit for trimming the complementary currents for substantially equalizing the base currents of the mirror transistors of the complementary current mirrors. The input of the trimming circuit is connected to the common node.
