Abstract:
Provided is an analog-to-digital (A/D) converter that may be used in an image sensor and a ramp signal generator that is used in an A/D converter. The ramp signal generator may generate a ramp signal and a reference voltage signal that include noise that has same noise characteristics that are input into the ramp signal, such that the signal to noise ratio (SNR) is improved and the image quality is also improved.
