Due to the wide usage of very low frequency (VLF) wave for research on natural phenomena, a VLF receiver application particularly with high sensitivity is absolutely required. The proposed VLF amplifier which is intended to produce high sensitivity for the frequency range of 10-30kHz is designed to have an output connectable to the soundcard of personal computer for further data processing. After achieving the optimum design, the hardware realization is then implemented on a printed circuit board (PCB). From the measurement result, it shows that the sensitivity is almost linear for the input signal lower than -12dBm and becoming quadratic for the input signal higher than -12dBm.[/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]Frequency ranges,Hardware realization,High sensitivity,Natural phenomena,Optimum designs,Printed circuit boards (PCB),Very low frequency[/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]amplifier,High sensitivity,Op-Amp,very low frequency (VLF) receiver[/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][/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/ICEEI.2015.7352520[/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]
