An FIR Filter Using Segmented Photodiodes for Silicon Photodiode Equalization

This letter presents a finite-impulse response (FIR) filter implemented using segmented photodiodes, which provides a bandwidth enhancement or a partial frequency response equalization for a silicon photodiode. The FIR filter utilizes an LC ladder network for its delay cells, where each segmented photodiode constitutes the ladder network. The measurement results show that the three-tap high-pass F...
