摘要

连续时间带通δ - σ调制器(CTBPDSMs)是有效的中频采样和简化接收机设计。比特流处理(BSP)可以与ctbpdsm阵列相结合,以实现高面积和功率效率的数字波束形成。BSP直接处理量化器的原始比特流输出,实现简单mux的数字处理。BSP和CTBPDSMs的组合在数字锁相环中也是有效的。新兴技术显示了CTDSM中多波段噪声整形的前景。

Continuous-Time Bandpass Delta-Sigma Modulators and Bitstream Processing: (Invited)
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.
