Influence of integrators in the performance of analog-to-information converters

Abstract

The development of analog-to-information converter if one the challenges in Compressed Sensing. In architectures proposed in the literature, the presence of integrators is a crucial point to the conversion. Hardware implementation of the integrators have great influence in the AIC performance, and using simulation in this work we analyze the AIC performance when some integrator parameters change. It was observed that there is a relation between cutoff frequency and AIC performance and depending on the value of this frequency low values of measurement occurs, and a high gain is necessary, what is a problem in hardware implementations.
