ABSTRACT:
A method of generating a phase value representative of a phase of a complex signal that includes an in-phase component and a quadrature-phase component includes determining a first sign for a first value and a second sign for a second value based on a quadrant occupied by the complex signal. The in-phase component is multiplied by the first value with the first sign, thereby generating a first multiplication result. The quadrature-phase component is multiplied by the second value with the second sign, thereby generating a second multiplication result. The first multiplication result, the second multiplication result, and a bias value are added, thereby generating the phase value for the complex signal.
