  • Patent number: 6891495
    Abstract: An analog-to-digital converter including analog-to-digital converting units connected in serial. The current comparator includes a current input terminal to receive a sampling current, a reference current input terminal to receive a reference current and a bit output terminal for outputting a bit signal. The current operation circuit includes a current output terminal for outputting a compared current according to the sampling current and the reference current. The operation controlling terminal selects the compared current according to the bit signal. The controlling terminal receives a clock signal to latch the bit signal. The analog-to-digital converting units output the bit signals in sequence in a period of the clock signal.
