Abstract :
In this paper, a general solution is proposed for the excess feedback loop delay issue for a discrete-time ΔΣ ADC. The corresponding low-distortion technique is also illustrated. Finally, the double-sampling ΔΣ ADC immune to the extra loop delay is described and verified through simulation.
