In this paper, Multi StAge Noise Shaping (MASH) architecture is employed to realize high noise reduction capability by noise shaping of ΔΣ modulator in quadrature-modulation envelope pulse width modulation (QM-EPWM). In the conventional ΔΣ modulator, it is disadvantageous that instability occurs in the third or higher order architecture. Therefore, by using MASH, it is possible to construct a modulator with high noise shaping with the same stability as the 1st-order one. However, as a harmful effect of using MASH, the output of the ΔΣ modulator is multi-level and it is impossible to digitally up-convert and output alternately using binary digital circuit. Therefore, in this paper we propose the parallel output MASH (PO-MASH) and QM-EPWM transmitter which use binary digital signal processing. However, since this uses a multi-level input digital amplifier. Therefore, we proposed using parallel / serial conversion not to use it. P/S is possible to up-convert and alternate output. We also performed a simulation using MATLAB. As a result, it was found that the modulation accuracy (EVM) relatively improved as compared with the transmitter using the conventional ΔΣ modulator. |
