Abstract
A modified low-power switched-capacitor integrator is proposed. It reduces power dissipation without increasing the thermal noise. The proposed integrator is parasitic-insensitive and allows a high linearity. A modified low-distortion self-coupled Delta-Sigma (ΔΣ) Analog-to-Digital Converter (ADC) is proposed to incorporate this new integrator. Analysis and simulations show that the high linearity can be achieved, even with mismatched parasitic capacitors.
