A stochastic noise model based excess noise factor expressions for staircase avalanche photodiodes
Ankitha E Bangera
Multistep staircase avalanche photodiodes (APDs) are the solid-state analogue of photomultiplier tubes, owing to their deterministic amplification with twofold stepwise gain via im…

Corrections to Friis noise factor formulas for cascade networks
Ankitha E Bangera
The signal-to-noise ratio of a multistage cascade network is often estimated using the well-known Friis' formulas for noise factors (or the noise figures in decibels). However, thi…

Mathematical proof of errors in Capasso's excess noise factor formula for an n-step staircase multiplier
Ankitha E Bangera
Solid-state devices such as multistep staircase avalanche photodiodes (APDs) are analogues to the photomultiplier tubes and are considered as a cascade-amplifier. The major source…
