The present disclosure provides a successive approximation method of three-state quantization and a successive approximation analog-to-digital converter circuit. The method includes for a first successive approximation of the arbitrary analog input signal between 0 and 1, comparing it with a quantization line 1/2; performing a second successive approximation according to a state of the first successive approximation; and by analogy up to a Nsuccessive approximation, in case that a certain successive approximation is the state three during the comparison process, ending the approximation, indicating that the interval where the signal is located has been found.
