Modeling Based on Elman Wavelet Neural Network for Class-D Power Amplifiers

12 Sep 2013Li WangJie ShaoYaqin ZhongWeisong ZhaoReza Malekian

In Class-D Power Amplifiers (CDPAs), the power supply noise can intermodulate with the input signal, manifesting into power-supply induced intermodulation distortion (PS-IMD) and due to the memory effects of the system, there exist asymmetries in the PS-IMDs. In this paper, a new behavioral modeling based on the Elman Wavelet Neural Network (EWNN) is proposed to study the nonlinear distortion of the CDPAs... (read more)
