A multiplying digital to analog converter includes first and second inputs for receiving first and second differential input signals. A differential amplifier has first and second differential input nodes and first and second differential output nodes. A first capacitor is coupled in series with a first switch between the first differential input node and the first input. The first capacitor is further coupled to at least one reference voltage supply node via one or more further switches. A second capacitor is coupled between the first differential input node and the first differential output node. A third capacitor is coupled between the first differential input node and the first input.

Pipelined ADC with constant charge demand

A method of successive approximation analog to digital conversion including: during a sample phase, coupling an input signal to a plurality of pairs of capacitors; and during a conversion phase, coupling a first capacitor of each pair to a first supply voltage, and a second capacitor of each pair to a second supply voltage.

Compact SAR ADC

A method for processing a digital signal includes an elementary processing including a radiofrequency transposition with a radiofrequency transposition signal and a digital to analog conversion of the transposed digital signal for delivering a radiofrequency analog signal. The digital to analog conversion is controlled by a control signal and a power control signal, the control signal having a frequency twice the frequency of the radiofrequency transposition signal. Each transition of the radiofrequency transposition signal occurs between two consecutive pulses of said control signal.

Method for performing a digital to analog conversion of a digital signal, and corresponding electronic device

A capacitive structure is provided that includes secondary stacks of superposed secondary electrodes that each include transverse branches connected via a longitudinal branch, means for connecting the superposed secondary electrodes of each of the stacks, first and second means for successively and alternately connecting so as to constitute a first secondary group of secondary stacks and a second secondary group of secondary stacks, at least two principal stacks of superposed principal electrodes which each include transverse branches that are connected via a longitudinal branch such that the transverse branches of the principal electrodes and the transverse branches of the secondary electrodes of the rows extend opposite one another and between one another in an alternating fashion, means for connecting the superposed principal electrodes of each of the principal stacks, and means for connecting the principal stacks so as to constitute a group of stacks of principal electrodes.
