SpletFloating-body partially depleted (PD) SOI MOSFET's exhibit excess low-frequency noise. For the first time, the origin of the excess noise is identified to be the shot noise associated with impact ionization current and body-source diode current. The shot noise, normally negligible as compared with flicker noise, is amplified in the device through the floating …
Spletlevels will be limited by the shot noise and the APD’s leakage current. Shot noise derives from the random statistical Poissonian fluctuations of the dark current, ID (or signal current). Dark current shot noise (IN(SHOT)) is normally given by iN(SHOT) = (2⋅q⋅B⋅ID) ½, for a PIN detector, where B is the system bandwidth. Splet• Similarly, the photo-electron shot noise variance is given by » where I 0 is the photon flux (photons/cm2s) and η is the quantum efficiency • So the total rms shot noise contribution from the sensor is • For example, with » J dark = 200nA/cm2 » A = (10µm)2 » t int = 30ms » I 0 = 1013 photons/cm2s » and η = 0.5 • we find
