access icon free Second-order VCO-based ΔΣ ADC using a modified DPLL

A novel purely VCO-based architecture for a second-order ΔΣ ADC is presented. 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.
