N2 - Quadrature Direct Digital Frequency Synthesis (QDDFS) is a device which can generate both sine and cosine simultaneously. This paper presents a method based on linear interpolation and least square error curve fitting to develop a phase compensation logic for the QDDFS. The architecture is suitable for VLSI implementation of QDDFS and is more area efficient and time efficient than look up table based approaches and Coordinate Rotation Digital Computer (CORDIC) based approaches respectively.
