List of current, in particular of the order of nanosatellites - amperes and regulator of using such a list

摘要

The present invention relates to a current generator ultra low and a voltage regulator using such a generator. The latter has: - a first assembly (41) of q of the transistors (p1, p2, p3) connected in current mirror, adapted to be connected to the supply voltage (vdd); - a second set of q - 1 of the transistors (n1, n2) connected in current mirror, each transistor being connected in series with a transistor of the first assembly; - a first transistor (n1) of the second assembly being connected in series with a transistor n3r, connected by a current mirror with a transistor n4, connected in series with a transistor (p3) of the first assembly. The transistor n3r operates in its linear region, the value of the current generated depends on the equivalent resistance of this transistor, the two transistors having a very long, so that the ratio l / w is very large.
