This report presents a low-power second-order Discrete-Time (DT) Delta-Sigma Modulator (DSM) for Internet of Things (IoT) applications. The design is based on the Noise Coupling (NC) structure, which has the advantage of fewer amplifiers, lower harmonics, and reduced idle tones. However, the NC stru...
