The present disclosure relates to an optical sensing system and an analog-to-digital converter. The optical sensing system includes a ramp signal generator, a digital logic circuit and a plurality of column circuits. The ramp signal generator is configured to generate a ramp signal and transmit the ramp signal to the column circuits. The ramp signal includes a signal of which a signal intensity varies with time, and a signal intensity variation rate of the ramp signal corresponds to an amplification factor of a photosensitive electric signal. Each column circuit is configured to receive photosensitive electric signal, and output a photosensitive gain signal to the digital logic circuit according to ramp signal and photosensitive electric signal. Photosensitive gain signal includes a digital signal corresponding to photosensitive electric signal of which signal intensity is amplified. The digital logic circuit is configured to calculate a digital sampling signal according to photosensitive gain signals.
