As the low level of ELF waves received by the antenna, an amplifier is considerably required to enhance receiver performance before data acquisition. The amplifier is built based on a low noise operational amplifier (Op-Amp) OP27 and intended to achieve high amplification in the frequency range of 1Hz to 50Hz. In order to avoid undesired frequency, the amplifier is equipped with the 2nd order low-pass active filter using the Sallen-Key topology with the cut-off frequency of 50Hz. The characterization results show that the proposed ELF receiver has maximum high gain of 60.8dB and high sensitivity for different low level inputs.[/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]Extremely low frequencies,Frequency ranges,High gain,High gain amplifier,High sensitivity,Low noise,Operational amplifier (op amp),Receiver performance[/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]Extremely low frequency (ELF),Low-pass filter (LPF),Operational amplifier (Op-Amp),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]This work is fully supported by the program of LP3 ITERA Grant, Institut Teknologi Sumatera, Indonesia, under the grant No: B/322/IT9.C1/PT.01.03/2019.[/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/TSSA51342.2020.9310828[/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]
