Abstract :
This paper explores predictive correlated double sampling (CDS) as a means of achieving good linearity and low power dissipation in low-voltage moderate-performance switched-capacitor (SC) delta-sigma modulators. The technique reduces the effect of the open-loop nonlinearity characteristic of an amplifier, thereby allowing the utilization of single-stage low-gain structures
