  • Patent number: 10212375
    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.
