Power-efficient decimation filters are critical for reducing the high-speed bitstream of a modulator to the Nyquist rate while maintaining a high Signal-to-Noise Ratio (SNR). Modern designs achieve significant power reductions (up to 28.6%) and area savings (up to 47.9%) by employing hybrid multi-stage architectures and specialized encoding schemes. 2.
