Abstract

Modified charge-pump based switched-capacitor integrator is a promising technique to reduce opamp power consumption. In this paper, design methodologies are introduced to incorporate such kind of integrator into a low-distortion delta-sigma modulator. A second-order delta-sigma modulator was designed and simulated to verify the proposed modulator topology.
