ABSTRACT:
A delta-sigma modulator circuit includes an n-level quantizer circuit that is configured to generate a quantized output signal responsive to an input signal. The n-level quantizer circuit includes n adder circuits that are configured to add a dither signal to n quantization levels to generate n dithered quantization levels, respectively and n comparator circuits that are configured to compare the input signal with the n dithered quantization levels to generate the quantized output signal.
