Desain Awal Analog Front-End Optical Transceiver untuk Aplikasi Visible Light Communication
Abstract: Analog Front-End
(AFE) is a part of physical layer (PHY) at Visible Light Communications (VLC)
system which has important things to transmit and receive the data. This
research is a preliminary study in designing AFE transceiver which consists of
LED driver and Trans-impedance Amplifier (TIA).
The results are used as advanced reference design of AFE system and also
to determine the modulations range (analog as well as digital). The design
verification is based on data transmission which generated by signal generator.
Square wave signal is used as digital modulation representative, and sinusoid
signal as analog modulation representatitive. The range of VLC channels is
about 50 cm with 0o angle. The result shows that digital modulation bandwidth
is about 1 KHz to 10 KHz frequency, and analog modulation bandwidth is from 200
KHz to 600 KHz. We also find a significant impact by adding 1 pF capacitor to
reduce noise gain. Furthermore, color filter testing is performed to
investigate the design performance.
