A ROM-Less Direct Digital Frequency Synthesizer Based on Hybrid Polynomial Approximation
In this paper, a novel design approach for a phase to sinusoid amplitude converter (PSAC) has been investigated. Two segments have been used to approximate the first sine quadrant. A first linear segment is used to fit the region near the zero point, while a second fourth-order parabolic segment is...
