A method of re-establishing the stability of a sigma-delta modulator having a plurality of integrator stages in cascade and a quantizer, achieving very short resetting times, a bit sequence corresponding to an instability state of the modulator is defined, the bit-stream output by the modulator is monitored to check whether it includes the instability sequence and, if the instability sequence is detected, the last integrator stage is reset and one or more preceding integrator stages are reset, progressively, until the instability sequence is no longer detected. |
