Performance of interpolation algorithms for PWM driven power amplifiers
Original language description
This paper presents performance study of digital PWM generator, which is the key component of the PWM AM transmitters. As only the natural PWM is baseband distortion-free modulation scheme, the digital PWM generator must calculate the intersection of themodulating signal and a piecewise linear reference signal, requiring a low-distortion interpolating algorithm. Moreover, the digital PWM generator output stage must offer exceptional time resolution and low jitter. Therefore, the accuracy of interpolating algorithm and time resolution of PWM generator are surely the critical points of the digital PWM generator design. Both phenomena are discussed in this paper. The different interpolating algorithms are tested for Signal-to-Sampling Noise Ratio (SSNR)and the digital PWM generator time resolution impact on spectral properties is simulated.
