Analog Multiplication in Random Demodulation Analog–to–Information Converters

Pasquale Daponte, Luca De Vito, Grazia Iadarola, Sergio Rapuano

Abstract

Aim of this paper is to compare in Analog-to-Information Converters the working principles of the two devices typically used to perform the operation of multiplication: mixers and analog multipliers. The comparison has been experimentally realized on two AIC prototypes based on the Random Demodulation principle: the former employing a mixer, the latter employing an analog multiplier.
