Abstract: Disclosed is a device for the conversion of a series signal received in the form of a low-amplitude, high-frequency differential signal into n parallel signals. The device uses a scheme derived from that of a static memory cell as a sample-and-hold unit and amplifier. The device continues to perform well when the differential signal comprises noise in common mode.

Abstract: An integrated circuit comprises at least one differential input stage. The differential input stage includes an input circuit and a shaping circuit. The input circuit comprises a first portion and a second portion for providing two pairs of differential signals. The propagation times of the first and second circuit portions are preferably substantially identical. The shaping circuit differentiates each of the two pairs of differential signals and combines them to obtain a single binary type of signal.

Abstract: A process and apparatus for sampling a serial digital signal (D), which includes phasing of the digital signal with a clock signal (C) and sampling the digital signal at delayed instants (Si), wherein the phasing is carried out in reference to the sampling instants. The phasing includes determining phasing test instants (Pi) which refer to the sampling instants (Si) to verify whether transitions of the digital signal are leading or lagging in phase relative to the phasing test instants. The determination of the phasing test instants is achieved by adding to each sampling instant (Si) a delay Y=kR/2, in which k is a positive whole odd number other than zero and R designates a pulse repetition period of the bits of the digital signal (D). The invention has particular utility in data processing and remote data processing systems, and to telecommunication systems.
