Abstract
A continuous time-sigma delta (CT-SD) data converter comprising a loop filter includes a first integrator having a first loop filter coefficient and a second integrator operatively coupled to the first integrator, the second integrator having a second loop filter coefficient, a modulator coupled to the loop filter, a reset switch coupled to the second integrator, a first peak detector operatively coupled in series with the second integrator to indicate an instability condition of a signal level exceeding a first threshold at an output of the second integrator, a second peak detector adapted to detect an input signal level to the CT-SD data converter, and a digital engine coupled to the first peak detector.
