SIGMA-DELTA MODULATOR |
摘要 |
A sigma-delta modulator comprising a plurality of filter stages in series with each other, wherein at least one of the plurality of filter stages is configured to provide a filter-output-signal; and a plurality of gain stages, each gain stage configured to provide a gain-output-signal. The sigma-delta modulator also includes a filter-output-switching-element configured to selectively couple the filter-output-signal to an input terminal of one of the plurality of gain stages; and a plurality of filter-input-switching-elements. Each of the plurality of filter-input-switching-elements is associated with one of the plurality of filter stages, wherein the plurality of filter-input-switching-elements are configured to selectively couple one of the gain-stage-output-signals to an input terminal of its associated one of the plurality of filter stages. |

1. A sigma-delta modulator comprising:
a plurality of filter stages in series with each other, wherein at least one of the plurality of filter stages is configured to provide a filter-output-signal; a plurality of gain stages, each gain stage configured to provide a gain-output-signal; a filter-output-switching-element configured to selectively couple the filter-output-signal to an input terminal of one of the plurality of gain stages; a plurality of filter-input-switching-elements, each of the plurality of filter-input-switching-elements being associated with one of the plurality of filter stages, wherein the plurality of filter-input-switching-elements are configured to selectively couple one of the gain-stage-output-signals to an input terminal of its associated one of the plurality of filter stages. |
