Samenvatting

Optical wireless communications systems are preferably designed to receive a strong signal over a wide field of view and with a large bandwidth. These are conflicting requirements. Recently it has been proposed and experimentally tested to split the surface area of the photodiode (PD) into N s by N p subareas, and to place N p rows in parallel with N s of these in series. This paper generates a deeper insight in this solution by analyzing the performance, in particular in combination with the low-noise transimpedance amplifier (TIA). In fact, by creating a virtual-ground (very low impedance) input, a TIA flattens the frequency response thereby mitigates parasitic PD capacitances. With decreased capacitance due to serial connection of PDs, noise is also less boosted at high frequency. Our analysis is compared with SPICE simulations.
