Abstract :
It was shown in prior work that, with proper digital calibration, ADCs with high static resolution can in principle be built without precise analog components. The paper offers some afterthoughts on this topic and connects it with beta expansions. It is suggested that, with proper calibration (but not without), ADC architectures based on the beta expansion can indeed achieve an effective resolution of m bits with analog circuit complexity linear in m and without precise analog components.
