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.
