The oscillator is constructed using a CMOS digital direct synthesizer (DDS) of AD9850 type from Analog Device. The use of AD9850 oscillator is due to its stability in generating the sine wave frequency of 13.56MHz required for the transmitter system of wireless power charging. While the E-class power amplifier is empowered by two cascaded MOSFETs of IRF510 and IRF620 types to obtain the high gain amplification. Prior hardware realization, a circuit EM simulator software is used to simulate the proposed design. The experimental characterization demonstrates that the power amplifier could amplify the sine wave output of AD9850 oscillator up to 36.3dB suitable for the desired application.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Analog devices,Digital direct synthesizers,Experimental characterization,Hardware realization,High gain amplification,Simulator software,Sine-wave frequencies,Wireless power[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Digital Direct Synthesizer (DDS),E-class power amplifier,oscillator,wireless power charging[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This work is partially supported by the postgraduate team research program (Penelitian Tim Pasca Sarjana) from the Ministry of Research, Technology and Higher Education, the Republic of Indonesia FY2017-FY2018.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/ICWT.2018.8527728[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
