This chapter is devoted to introducing the context of the presentedwork. Motivations for CMOS implementations of low-power systemon-chip applications are explained first. Then, limitations of the stateof-the-art CMOS analog techniques are studied. As a result, the InstantaneousCompanding Theory is chosen here as the most efficientand complete signal processing alternative for very low-voltage operation.A short overview of this theory is presented through a generalizeddevice-independent nomenclature. Problems on migration from previousbipolar implementations of this theory to modern CMOS processesare argued. Hence, the final goal of this work is defined as the researchon novel CMOS analog circuit techniques compatible with CMOS technologies,which should exploit the low-voltage capabilities of Log Compandingprocessing.
