The LED driver performances are already tested with three scenarios approach and it can work properly. Those approaches are 1) single carrier signal generated by signal generator with offset null as an input signal, 2) integrated with the digital block, i.e. Digital-to-Analog converter (DAC) board which has DC component as an input signal, and 3) using the audio signal as input. The contribution in this paper i.e. 1) the LED driver was simply designed and it could be used for signal with multilevel amplitude format, e.g. audio signals, video signals, orthogonal frequency division multiplexing (OFDM) signal format, etc.; 2) low-cost platform which is built from inexpensive general DIP OP-AMP, 3) can dial up 50 kHz of bandwidth; 4) no flicker effect, therefore harmless for human eyes; 5) light weight implementation and 6) simple to operate with manual tuning. Our proposed LED driver is divided into three stages where each of them, have the main functions, i.e. a) DC-offset remover circuit to remove signal input with has DC signal characteristic, DC-offset summer circuit with a variable amplifier as signal conditioning, and voltage follower transistor.[/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]Data transmitter,Indoor environment,Indoor lightings,LED drivers,Low costs,Low rates,Signal formats,Voltage follower[/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]LED driver circuit,Low-cost,Low-rate data transmission,Visible light communication[/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/10.1016/j.ijleo.2017.11.180[/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]
