Programmable sample rate analog to digital converter and method for use therewith
摘要:
A programmable sample rate ADC includes a delta sigma modulator for producing a digital signal, and a programmable decimation filter, that includes X stages of integration, a down-sampling stage for down-sampling by a factor of N, and Y stages of differentiation. The programmable sample rate ADC produces a digital output signal at a substantially constant frequency.
