ROM-Less Phase to Amplitude Converter Using Sine Wave Approximation Based on Harmonic Removal from Trapezoid Wave

摘要

This paper proposes a new sine wave approximation method for the PAC of DDFS. Sine wave is approximated by removing the harmonic components from trapezoid waveform. Experimental results show that the proposed PAC is advantageous in the SFDR range less than 60 dBc due to its small hardware cost.
