An analog-to-digital converter (100) (ADC) includes a dither signal generator (107) configured to add an analog dither signal (114) to the analog input signal (102) of the ADC prior to digitization (i.e., quantization). The amplitude of the either signal is selected based upon the power levels of one or more carriers present in the bandwidth for which the ADC is designed to operate. Addition of the dither signal to the input signal in the analog domain reduces quantization noise such as conversion spurs that result from non-linearities in the ADC transfer function. <IMAGE> |
