1. An analog-to-digital converting device configured to convert an analog signal into a digital signal, the analog-to-digital converting device comprising:
a meta-stability detection unit configured to output a meta-stability signal based on a comparison result, wherein the comparison result is determined by comparing a comparison voltage of each bit of the digital signal with the analog signal;
a counter configured to count a number of times that the comparison voltage of each bit of the digital signal is compared with the analog signal; and
a control logic configured to detect a bit at which meta-stability has occurred from among bits of the digital signal based on the meta-stability signal and the counted number,
wherein the counter is further configured to count the counted number by counting pulses of a clock signal input to the counter.
