Two-step continuous-time incremental sigma-delta ADC

• A two-step continuous-time (CT) incremental sigma-delta (I Sigma Delta) ADC, which enhances the performance of conventional CT I Sigma Delta ADCs, is proposed. By pipelining two second-order CT I Sigma Delta ADCs, the proposed two-step architecture can achieve high resolution without sacrificing the conversion rate. Compared to other alternatives, the two-step CT I Sigma Delta ADC exhibits the freedom of adjusting its accuracy and speed independently while featuring quite relaxed circuit specifications.
