A Hybrid-Loop Structure and Interleaved Noise-Shaped Quantizer for a Robust 100-MHz BW and 69-dB DR DSM

A continuous-Time delta–sigma modulator (CT-DSM) excels at high-bandwidth (BW), high-dynamic-range analog-to-digital conversion. However, CT-DSMs suffer from PVT variation, high sensitivity to timing errors, and are restricted in sampling rate. This work proposes a hybrid-loop (HL) DSM architecture to mitigate the disadvantages of CT-DSM while providing similar performance. This work also introduc...
