Abstract
Continuous- Time Bandpass Delta-Sigma Modulators (CTBPDSMs) are effective for IF sampling and simplify receiver design. Bitstream processing (BSP) can be combined with an array of CTBPDSMs to enable highly area and power efficient digital beamforming. BSP directly processes the raw bit-stream outputs of the quantizers, enabling digital processing with simple MUXs. The combination of BSP and CTBPDSMs is also effective in a digital PLL. Emerging techniques show the promise of multi-band noise-shaping in a CTDSM.
