Abstract:
The present invention provides a continuous-time delta-sigma modulator comprising two ADCs. One of the ADC is configured to generate MSBs of an output signal of the continuous-time delta-sigma modulator, and the other ADC is configured to generate LSBs of the output signal. In addition, the two ADCs sample an output of a loop filter at different times, but the MSBs and LSBs are feedback to the loop filter simultaneously.
