In the following project, the VLSI (Very Large Scale Integration) design of a simple mixed hardware was carried out, capable of extracting sinusoidal stimuli encoded in Pulse Density Modulated (PDM) signals through sigma-delta modulation for exciting Device Under Test (DUT) in mixed-signal integrated circuits. The main feature of this system is its programmability, which allows the user to select, according to their needs, the parameters of the waveform they wish to generate. Additionally, a signal digitizer is developed to extract the response signals of the excited blocks in digital format. Although the focus of the work is on the design of the integrated hardware, a Matlab® algorithm was developed to obtain PDM signals. This software version allows verifying the principle of operation of the developed system. The hardware was designed using 0.12 µm CMOS technology, to be powered with simple and dual  ±1.5V and  ±1.0V sources. Signal digitizer resolutions of 5 bits were achieved with an oversampling of 10.
