Abstract:
Slaved supply for linking a slave element linked to a master element by a serial link, the master element comprising a master module for regulating the electrical supply voltage of a master output circuit, delivering master digital output signals, and of a master input circuit, receiving slave digital output signals by way of said serial link, the slave element comprising, supplied by a slave electrical supply voltage, a slave input circuit receiving the master digital output signals by way of said serial link, a slave output circuit delivering the slave digital output signals and a slave module for regulating the electrical supply voltage of the slave input and output circuits, wherein said slave module for regulating the electrical supply voltage comprises:means for sampling and for detecting the peak value of said master digital output signals received by way of said serial link, said sampling and detecting means delivering a sampled peak value of said master digital output signals; means for slaving said slave supply voltage of said slave input and output circuits to a value substantially equal to that of the sampled peak value of said master output signals, thereby making it possible to deliver slave digital output signals whose peak amplitude is substantially matched to the peak amplitude of the master digital output signals.
