Hybrid FIR/IIR analog filter |
摘要 |
A hybrid FIR/IIR analog filter for filtering the coarsely quantized output of a sigma-delta modulator for digital-to-analog conversion. The functions of an FIR and IIR filter are combined into one circuit to gain the benefits of both, while requiring fewer taps than the present FIR approach, and requiring less area as an IIR filter.
