摘要： A clock and data recovery circuit in accordance with an embodiment of the inventive concept includes a phase locked loop configured to receive a data stream into which an additional bit is inserted at every reference period to generate parallelized data and a clock signal, and a first detector circuit configured to determine whether the parallelized data is locked based on a bit-conversion of the data stream according to an insertion of the additional bit. The bit-conversion is executed with respect to the additional bits according to a predetermined protocol, or is executed with respect to at least one bit from among data of the data stream between a current one of the additional bits and a next one of the additional bits.

摘要： An electronic device includes a pixel array that outputs a raw image including color pixels and specific pixels, a logic circuit that outputs a first binned image by performing first binning on pixels in a row direction for each unit kernel of the raw image, and a processor that outputs a second binned image by performing second binning on the first binned image. When a unit kernel includes at least one of the specific pixels, a column to which the at least one specific pixel belongs is read out at a readout timing different from a readout timing of a column to which none of the specific pixels belong and undergoes the first binning. The second binning combines a third binned image of the column to which none of the specific pixels belong with a fourth binned image of the column to which the at least one specific pixel belongs.

摘要： A programmable gain amplifier includes a sampling circuit, a source follower, a first capacitor and an error amplifier. The sampling circuit is configured to perform correlated double sampling on an input signal using a reference voltage. The first capacitor is connected between the sampling circuit and the source follower.
