Abstract: Compressed Sensing (CS) is a technique for the reconstruction of a waveform using a number of measurements that is potentially much smaller than the number of samples at the Nyquist rate. CS hinges on a simple early processing of signal samples and is the basis for the so called Analog-to-Information Converters (AIC) where one tries to match resources needed for acquisition with the actual amount of captured information.

This tutorial starts from CS basics and develops recent techniques for the joint design of hardware and algorithms for AICs based on lightweight signal adaptation. Design flows will be exemplified for analog and digital implementations with considerations on power consumption and effect of non-idealities validated by simulation and measurements.

Configurations and conditions in which AIC yields significant improvements over classical acquisition mechanisms will be identified. The discussion will also cover other advantages of the early-processing entailed by CS, e.g., the possibility of embedding partial but zero-cost security into the resulting acquisition processing (thus avoiding the need of dedicated cryptographic stages in non-critical applications) or the possibility to be effectively used in the realization of body-area-network/IoT nodes for biomedical application, a possibility which will be explored in the tutorial.
