The present invention relates to a method of compensating for the disturbances
due to the demultiplexing of an analogue signal with regard to a circuit comprising
N data lines, wherein the demultiplexing is carried out by sample-and-hold circuits
whose input receives the analogue signal and whose output is connected to one of
the N data lines, the N sample-and-hold circuits being operated in succession by
a sampling signal (ECHi).
During the application of the sampling signal (ECHi, V1) to one of
the sample-and-hold circuits, an opposite compensation level (V3) which
is lower than the level of the sampling signal is applied to the N-1 sample-and-hold circuits.
Application in particular to LCD screens.
