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.
