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…
A Noise Model for Multilayer Graded-Bandgap Avalanche Photodiodes
Ankitha E. Bangera
Multilayer graded-bandgap avalanche photodiodes (APDs) are the future deterministic photomultipliers, owing to their deterministic amplification with twofold stepwise gain via impa…
Correction to Friis Noise Factors
Ankitha E. Bangera
The signal-to-noise ratio of a multistage cascade network is often estimated using Friis formulas for noise factors (or the noise figures in decibel). In this letter, the correct f…
