Due to optical wireless link power budget considerations, the receiver is required to have a large collection area. Typical large photodetection area commercial wireless photodetectors has capacitance are around 100-300pF compared to 50pF in fiber link. Hence, techniques to reduce the effective detector capacitance are required in order to achieve a low noise and wide bandwidth design. The bootstrap transimpedance amplifications (BTA) technique offers the usual advantages of the transimpedance amplifier together with an effective capacitance reduction technique for optical wireless detector. In this chapter, analysis on the shunt-BTA for input capacitance reduction will be reported. Significant bandwidths enhancement was achieved by shunt-BTA compared to transimpedance front-end.
