A CMOS integrated circuit incorporating both logic functions and analog functions. The latter are subjected to noise from the logic transitions by means of supply conductors. To avoid disturbing the rest point of an amplifier by this supply noise, without using compensation circuits which would increase the number of pins of the integrated circuit, it is proposed to supply a pair of complementary transistors forming an amplifier stage by identical incoming and outgoing current generators. These generators are transistors copying a current from a current mirror circuit which includes a pair of complementary transistors connected between the two power supply lines.
