ABSTRACT:
The manufacturing, fluctuations in electrical parameters of I.sup.2 L double-collector current source transistors each of which is connected in series with a bias transistor having a base zone common with the base zone of the other bias transistors, are compensated by means of a bias voltage generator whose output voltage is fed to said common base. The bias voltage generator consists of a current mirror comprising a further I.sup.2 L double-collector current source transistor and a further bias transistor having the same configuration and conductivity type as the I.sup.2 L double-collector current source transistors and the bias transistors.
