Optical receiver bandwidth enhancement using bootstrap transimpedance amplification technique

Optical wireless link operates in high noise environments owing to ambient conditions such as sun for outdoors and fluorescent for indoors. The performance of free-space optics is subjected to several atmospheric factors like environmental temperature, fog, smoke, haze and rain. Signal-to-noise rati...
