The proposed architecture achieves in-band second-order quantisation noise shaping. The proposed ADC is highly digital and well suited for design in scaled technologies. The architecture has been validated with MATLAB Simulink based models. %@ 0013-5194 %T Second-order VCO-based ΔΣ ADC using a modified DPLL %B Electronics Letters %D July 2016 %V 52 %N 14 %P 1204-1205 %I Institution of Engineering and Technology %U https://digital-library.theiet.org/;jsessionid=61olc28de1n88.x-iet-live-01content/journals/10.1049/el.2016.1428 %G EN
