Abstract

This paper presents a wideband and energy-efficient single-loop 3 order CTSDM enabled by an ELD-SAB-Merged integrator and a 3-stage opamp. We utilize only a single DAC and opamp to accomplish the ELD compensation in the SAB structure. While featuring a PSQ technique and a 1 order NS-SAR, the 28nm prototype achieves a 74.4dB SNDR in a 50MHz BW and consumes 10.4mW with 171.2dB FoM.
