ABSTRACT:
In the present invention is described a forward feed sigma delta modulator of higher order having automatic saturation detection and recovery. The modulator is separated into two parts which are connected together when there is no saturation, and disconnected when saturation is detected and recovery takes place. The first part contains an integrator and input output circuitry to allow continuous operation of the modulator. The second part contains additional integrators to provider for a higher order modulator and the saturation detector. The modulator can be constructed of single ended or differential switched capacitor technology, and there is a digital saturation detection scheme.
