Abstract
Various embodiments of the present invention provide systems and methods for phase compensated harmonic sensing. For example, a circuit for harmonics calculation is disclosed that includes a phase difference estimation circuit and a phase offset compensation circuit. The harmonic calculation circuit is operable to calculate a first harmonic based on a periodic data pattern and a second harmonic based on the periodic data pattern. The phase difference estimation circuit operable to calculate a phase difference between the first harmonic and the second harmonic. The phase offset compensation circuit operable to align the second harmonic with the first harmonic to yield an aligned harmonic.
