A 3.7-mW 12.5-MHz 81-dB SNDR 4th-Order Continuous-Time DSM With Single-OTA and 2nd-Order Noise-Shaping SAR

This article presents a hybrid 4th-order delta–sigma modulator (DSM). It combines a continuous-time (CT) loop filter and a discrete-time (DT) passive 2nd-order noise-shaping SAR (NS-SAR). Since the 2nd-order NS-SAR is robust against PVT variation, the stability of this 4th-order DSM is si...
