Abstract
The present invention relates to a quick response power supply switching device. It also relates to a power supply network equipped with such a switch. The electrical power supply is connected to a set of blocks, the device comprises at least one switch () connecting the power supply (VDD) and the block (), the value of the power supply current passing through the switch being controlled according to the difference between the power supply voltage (VDD) at the level of the other blocks and voltage threshold. The invention applies notably to all integrated circuits of recent technology in which it is important to reduce the leakage currents of the transistors in the unused circuit parts. The invention thus applies particularly to most systems powered by cell or battery and more particularly to portable telephone circuits.
