ABSTRACT:
Devices, systems, and methods for providing delta-sigma modulation in conjunction with analog-to-digital or digital-to-analog signal conversion are disclosed. The delta-sigma modulator and delta-sigma converter include dynamically-scalable coefficients, which, at relatively low signal amplitudes, allow the delta-sigma modulator and delta-sigma converter to modulate the signals using a first noise transfer function and, at relatively greater signal amplitudes, allow the delta-sigma modulator and delta-sigma converter to modulate the signals using a second noise transfer function.
