Switching device of the electrical power supply has a rapid response and electrical power supply network relates to such a switch.

摘要

The present invention relates to a device for switching power supply to the fast response. It also relates to an electrical power supply network, equipped with such a commutateur.l' electrical supply is connected to a set of blocks, the device comprises at least one switch (3) connecting the power supply (vdd) and the block (1), the value of the supply current passing through the switch being controlled as a function of the difference between the supply voltage (vdd) at the level of the other blocks and a threshold appliquie tension.l' invention is especially to all the integrated circuits of recent design in which it is important to reduce the leakage currents of transistors of the portions of circuits which are not used. The present invention applies particularly to the majority of the systems supplied by cell or battery and more particularly for the circuits of portable telephones.
