A comparison circuit is provided and includes first and second comparators and a first time-to-digital comparator. The first comparator with a first offset voltage receives an input signal and generates a first comparison signal and a first inverse comparison signal. The second comparator receives the input signal and generates a second comparison signal and a second inverse comparison signal. The first offset voltage is larger than the second offset voltage. The first time-to-digital comparator receives the first comparison signal and the second inverse comparison signal and generates first and second determination signals according to the first comparison signal and the second inverse comparison signal. The first and second determination signals indicate whether a voltage of the input signal is larger than a first middle voltage. The first middle voltage is equal to a half of the sum of the first offset voltage and the second offset voltage.
