A Continuous-Time Delta-Sigma Modulator Using ELD-Compensation-Embedded SAB and DWA-Inherent Time-Domain Quantizer.

This paper presents an energy-efficient third-order 3 bit continuous-time delta-sigma modulator (CTDSM). In this work, several architectural and circuit techniques are adopted to facilitate a low-power modulator. In the loop filter design, a single-amplifier biquad (SAB) topology is incorporated to realize the desired transfer function. With the SAB architecture, only two amplifiers are needed for...
