Abstract
A method for detecting saturation in a cascaded ΔΣ ADC can include receiving an output of the cascaded ΔΣ ADC, determining a magnitude of the output, and squaring the magnitude. The squared magnitude can be added to a feedback signal, wherein the sum represents a saturation signal. The saturation signal can be filtered and then amplified, wherein the amplified, filtered saturation signal is the feedback signal. The saturation signal can then be compared to a threshold to determine whether the cascaded ΔΣ ADC is in saturation.
