Sigma-delta Modulator for N-digit Fractional Divider
Zhang Sizhong, Asic System · Journal of Electron Devices · 2002
The article analyses the improvement of sigma delta to S/N, introduces the application of sigma delta in A/D into N digit fractional divider, simply describes the improvement of sigma delta to the output phase vibration of N fractional divider, raises the conception of repeatedly cycled utilization of a sigma delta accumulator replacting multiple accumulators.
