Abstract (en)
[origin: US4442398A] An integrated circuit constituting a current generator formed by CMOS technology comprises a first pair of similar transistors, one of which recopies the current of the other, subject to a proportionality factor; a second pair of similar transistors, one of which recopies the source voltage of the other; a third pair of similar transistors having different threshold voltages in contrast to the other pairs. A resistor is placed in series with one of the transistors of the third pair in order to compensate for the difference between the threshold voltages, an additional transistor being provided for recopying the current in one of the transistors aforementioned. The current thus produced is stable in time as well as independent of temperature and of the circuit supply voltage.
