A 70-MHz Bandwidth Time-Interleaved Noise-Shaping SAR-Assisted Delta-Sigma ADC With Digital Cross-Coupling in 28-nm CMOS by Lucas Moura Santana, Ewout Martens, Jorge Lagos, Piet Wambacq, Jan Craninckx

“…This work presents a <inline-formula> <tex-math notation="LaTeX">$2\times $ </tex-math></inline-formula> time-interleaved (TI) delta-sigma modulator (DSM) analog-to-digital converter (ADC) leveraging a 6-b noise-coupled (NC) noise-shaping (NS) SAR quantizer. A novel technique to implement the noise coupling mid-quantization is presented to relax the timing bottleneck by parallelizing the operations needed for coupling. …”
