    Abstract: An analog-to-digital converting circuit includes a first amplifier configured to output a first output signal by comparing a pixel signal output from a pixel array with a ramp signal, and a second amplifier configured to generate a second output signal based on the first output signal. The second amplifier includes a first transistor configured to provide a power supply voltage to a first output node in response to the first output signal, a second transistor connected with a capacitor through a bias node, wherein the second transistor is configured to turn on in response to an auto-zero signal, a current source connected with the first transistor through the first output node, the current source configured to generate a power current based on a voltage level of the bias node, and a third transistor connected with the current source.

    Abstract: An operation method of an electronic device including a core includes reading first status information from a first status register of a first functional block driven independently of the core, reading second status information from a second status register of a second functional block driven independently of the core, reading first change information from a first flag register of the first functional block, reading second change information from a second flag register of the second functional block, determining whether an operation status of the electronic device is any one status of an idle status and a busy status, based on the read first and second status information and the read first and second change information, and operating in an operation mode corresponding to the determined operation status.

    Abstract: A system includes: a nonvolatile memory; a memory controller configured to control the nonvolatile memory, the memory controller including a first buffer memory for temporarily storing write data to be written to the nonvolatile memory; and a second buffer memory having a lower operational speed and a higher memory capacity than the first buffer memory. The memory controller is configured to transmit the write data from the first buffer memory to the second buffer memory and to the nonvolatile memory, and to release an operational state of the first buffer memory after transmitting the write data from the first buffer memory to the second buffer memory and to the nonvolatile memory. Writing additional write data to the first buffer memory is prohibited prior to the release of the operational state of the first buffer memory, and is permitted after the release of the operational state of the first buffer memory.

    Abstract: An electronic device for controlling a power supply is provided. The electronic device includes a power unit configured to supply power, a power management unit configured to receive a supply of power from the power unit and to distribute the supplied power, a flood sensing unit connected to the power unit and located in a part of the electronic device most subject to flooding or fluid penetration, and a power control switch configured to, if a voltage level of the flood sensing unit is a first level indicating no detected flooding or fluid penetration, electrically connect the power unit and the power management unit to each other, and if the voltage level of the flood sensing unit is a second level indicating a detected flooding or fluid penetration, interrupt an electrical connection between the power unit and the power management unit.
