摘要

This article presents a 12-bit column-parallel two-step single-slope analog-to-digital converter (SS ADC). With the merging of analog memory capacitor and input sampling capacitor, the proposed two-step SS ADC realizes simultaneously residue storage and zero-cross detection. The fixed decision point guarantees a static comparator offset. A constant input common-mode level resistor ramp generator, ...
