Abstract

The performance of receiver system for the optical wireless communication is greatly determined by the performance of the front-end. However, large detection area required in optical wireless application produces high detector capacitance hence limits the bandwidth performance of the system. Thus, techniques to reduce effective detector capacitance are required to increase the receiver sensitivity, bandwidth and noise performance. A lot of papers have been previously reported successful techniques to enhance the bandwidth by employing bootstrapping technique. This paper introduces a series-shunt bootstrapping technique which exploits a series-shunt positive capacitive feedback. The modeling of the circuit is done by utilizing MATLAB. This technique boosts the bandwidth up to 1.04 GHz.
