Noise Analysis in VLC Optical Link based Discrette OPAMP Trans-impedance Ampl...TELKOMNIKA JOURNAL
To design Visible Light Communication (VLC) system, there are several requirements that needs
to be met. One of the requirements is an active component selection (e.g. Op Amp). As an ideal
communication system, VLC system has to be able to provides wide bandwidth access with minimum
noise. The Transimpedance amplifiers (TIAs) is one of main components in optical system which is placed
in the first stage of receiver system. It is used to convert the current output from photodiode to voltage. We
have designed a 1 MHz fGBW TIA with low noise (in μVrms range). This paper aims to explain the design
and implementation of TIA circuit with photovoltaic topology which cover empirical calculations and
simulation of TIA’s bandwidth and its noise sources, i.e. resistor feedback noise, current noise, voltage
noise and total noise based on RSS. The OP-AMP is chosen from Texas Instruments product, OPA 380,
and photodiode is chosen from OSRAM, SFH213, then simulated by TINA-TI SPICE® software. The noise
in TIA circuit is analyzed clearly. The developed kit is ready to be implemented in VLC system.

Extend Your Journey: Considering Signal Strength and Fluctuation in Location-...Chih-Chuan Cheng
Reducing the communication energy is essential to facilitate the growth of emerging mobile applications. In this paper, we introduce signal strength into location-based applications to reduce the energy consumption of mobile devices for data reception. First, we model the problem of data fetch scheduling, with the objective of minimizing the energy required to fetch location-based information without impacting the application’s semantics adversely. To solve the fundamental problem, we propose a dynamic programming algorithm and prove its optimality in terms of energy savings. Then, we perform postoptimal analysis to explore the tolerance of the algorithm to signal strength fluctuations. Finally, based on the algorithm, we consider implementation issues.We have also developed a virtual tour system integrated with existing web applications to validate the practicability of the proposed concept. The results of experiments conducted based on real-world case studies are very encouraging and demonstrate the applicability of the proposed algorithm towards signal strength fluctuations.
