Abstract
A multirate architecture for implementation of SD modulator is proposed in this paper. The performance of the called MM (multirate-multibit) SD modulator is the same that a conventional multibit SD modulator working at the clock rate of the first integrator, but the ADC in the forward path is replaced by an increase at the clock rate of the second integrator. Theoretical and simulation results are presented
