摘要： An analog-to-digital converter includes a comparison signal generation unit and a control unit. The comparison signal generation unit determines a logic level of a comparison signal by comparing an input signal with a selected reference signal based on a switch control signal in a first comparison mode, and by comparing a difference voltage with a ramp signal based on the switch control signal in a second comparison mode. The difference voltage is generated based on the input signal and the selected reference signal such that a level of the difference voltage is lower than a fine voltage level corresponding to a voltage level of the selected reference signal in the second comparison mode. The control unit generates the switch control signal based on the comparison signal and a mode selection signal.

摘要： An analog to digital converter (ADC) can include a multi-input comparison unit configured to compare a pixel voltage from an image sensor, a comparison voltage comprising a stepped voltage modified during a coarse mode of operation, and a ramp voltage comprising a ramped voltage modified to one another during a fine mode of operation, to provide a comparison result signal that indicates whether the comparison voltage combined with the ramp voltage is greater than or less than the pixel voltage. A selection control signal generation unit can receive the comparison result signal and a mode control signal, to indicate the coarse or fine mode, to provide a selection control signal allowing modification of the comparison voltage in the coarse mode and to hold the comparison voltage constant in the fine mode. A reference voltage selection unit can receive the selection control signal to control modification of the comparison voltage.
