Abstract: An analog signals generating device comprises a current pump controlled by a control code generated by a module for calculating the digital code with shaping of noise. The calculation module receives as input a digital signal representative of the analog signal to be generated and comprises at least one quantizer and a quantization error compensating stage. The current pump comprises two groups of at least one electric current generator and two groups of at least one switching means, the switching facilities being controlled by the control signal and causing the electric currents to flow between the electric current generators and the inputs of a differential amplifier exhibiting a predominantly capacitive input impedance and connected in series between the two groups of switching means.

Abstract: A device processes a received radio signal. Circuitry formulates voltage samples of the radio signal. Analog processing of those samples is performed. Then, digital processing is performed on the output of the analog processing. The circuitry for formulating voltage samples is configured to ensure a processing of the samples prior to the digital processing.

Abstract: Methods and apparatuses for backing up data to a database are provided. A specified data set to be backed up is broken down into a plurality of data blocks, each data block is associated with a data block digest, and the data blocks and associated data block digests are stored in the database. When one or more data blocks are subsequently changed, an update to the backup may be performed by adding to the backup data only the data blocks that have changed since the initial backup. Methods and apparatuses for restoring backup data from a database are also provided. Timestamp information associated with the data blocks in the database is used to select the data blocks to be restored.
