Abstract
A phase deviation compensation method and device are provided. The method may include: a first sine analog signal and a first cosine analog signal are acquired; the first sine analog signal is converted to a corresponding first sine digital signal, and the first cosine analog signal is converted to a corresponding first cosine digital signal; a sampler is controlled to sample the first sine analog signal and the first cosine analog signal according to variations of pulse edges of the first sine digital signal and the first cosine digital signal, to acquire at least one sine sampled signal and at least one cosine sampled signal; a phase deviation is determined; and phase compensation is performed on the at least one sine sampled signal and the at least one cosine sampled signal according to the phase deviation.
