TIA convert the current (I) into voltage (V). Application TIA design depend of objectives requirement system, for high speed as well as high-band, low noise, low power and others. This paper explains the empirical experiment of TIA for high-band VLC with over 1-MHz Gain Bandwidth Product (GPWP) estimated. We implement general topology mode: as photovoltaic. The selection of the best resistor feedback (Rf) and compensator (Cf) are presented, we compare simulation approach against real implementation. The OP-AMP chosen from Texas Instruments® product, OPA 656. The TINA™ SPICE® simulator used as simulation’s tool. This research contribution lies in applied of engineering design methodology with detailed step to develop major VLC system, we focus on photodiode amplifier only. By depth analysis, can be known next research addresses and obtain the best results without trial and error methods.[/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]Empirical experiments,Gain-bandwidth products,OPA656,Precision instrumentation,Simulation approach,Trans impedances,Trial-and-error method,Visible light communications (VLC)[/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]OPA656,Trans-impedance Amplifier (TIA),Visible Light Communications (VLC)[/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/ICITACEE.2016.7892405[/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]
