    Abstract: An analog-to-digital converter includes a comparator, a switch, and a counter circuit. The comparator is configured to generate a comparison signal by comparing an analog signal received through a first signal line and a reference signal received through a second signal line. The switch is coupled between the first signal line and the comparator. The switch is open before the analog signal is applied to the first signal line to disconnect the first signal line from the comparator, and is closed after the analog signal is applied to the first signal line to provide the analog signal to the comparator. The counter circuit is configured to generate a digital signal corresponding to the analog signal by performing a count operation in synchronization with a count clock signal based on the comparison signal.

    Abstract: An image sensor can include a pixel array including a plurality of unit pixels and a row driver arranged in a matrix form that includes a plurality of rows and a plurality of columns. Respective ones of the unit pixels may convent an incident light to an electric signal and may store the electric signal. The row driver may sequentially scan the plurality of rows and may sequentially perform an electronic shutter operation and read-out operation. The electronic shutter operation may reset the stored electric signal in each unit pixel and the read-out operation may read-out the stored electric signal in each unit pixel. The electric shutter operation can include a preliminary shutter operation and a main shutter operation which are sequentially performed on one row. The row driver may overlap the main shutter operation on a first row and the preliminary shutter operation on a second row.

    Abstract: A correlated double sampling (CDS) circuit may include a sampling circuit and a switching circuit. The CDS circuit may perform a CDS operation on a reset component of an input signal and an image component of the input signal based on a ramp signal, and the CDS circuit may generate an output signal. The switching circuit may include an auto-zero switch that connects a first input terminal receiving the input signal to an output node in response to an auto-zero control signal during an auto-zero interval. The switching circuit may connect a first terminal of the auto-zero switch to a reference voltage in order to cutoff a leakage current flowing to the auto-zero switch in response to a first boosting control signal during a first comparison interval and a second comparison interval. The output signal may be provided at the output node.

    Abstract: An ambient light sensor includes a photoelectric conversion unit, a current control unit, a signal conversion unit and a comparison unit. The photoelectric conversion unit provides a photo current having a magnitude corresponding to illuminance of incident light to a first node. The current control unit generates a control current exponentially proportional to an elapse time based on a clock signal, provides the control current to the first node, and outputs a digital code corresponding to the elapse time in response to a reset signal. The signal conversion unit generates a comparison voltage logarithmically proportional to a sum of the photo current and the control current. The comparison unit generates the reset signal by comparing a magnitude of the comparison voltage and a magnitude of a reference voltage. The ambient light sensor generates the digital code effectively representing illuminance of ambient light that eyes of a human being perceives.
