Phase-Locked Loop with Inverse Tangent based Phase Detection
Advances in Electrical and Computer Engineering, 2021 In this paper, a novel closed-loop synchronization algorithm is proposed based on the linear phase angle detection. The linear phase detection is performed by the inverse tangent (atan2) trigonometric function, while the frequency tracking is performed
