Analog-to-information　converters　(AICs)　provide　sub-Nyquist　sampling　rates　by　signal　bandwidth　compression,　leading　to　continuous　charge　accumulation　within　the　circuit.　The　amplitude　of　the　compressed　signal　sometimes　exceeds　the　voltage　range　of　the　circuits,　thereby　impacting　its　precision.　The　incorporation　of　voltage　boosting　and　interpolation　into　flash　AIC　is　suggested　to　resolve　this　problem.　A　voltage　boost　method　with　a　charge　pump　generates　several　reference　levels　for　a　comparator.　The　output　of　the　comparator　is　subsequently　segmented　and　quantified　by　hybrid　domain　quantization,　resulting　in　an　interpolated　digital　sequence.　The　experimental　results　demonstrate　that　the　proposed　flash　AIC　is　capable　of　processing　a　signal　with　an　amplitude　range　of　1　V　while　operating　on　a　supply　voltage　of　0.8　V.　It　samples　the　signal　at　a　maximum　bandwidth　of　25　MHz,　at　a　rate　of　12.5　MHz,　and　achieves　4-bit　quantization　through　the　use　of　a　1-bit　comparator.　Compared　with　the　current　AIC　designs,　the　flash　AIC　achieves　a　2x　improvement　in　the　Figure　of　Merit　(FoM),　while　incurring　only　a　negligible　compromise　on　the　reconstructed　signal-to-noise　ratio　(RSNR).　©　2025　IEEE.
