Previous studies have demonstrated a close relationship between early Parkinson's disease
and functional network abnormalities. However, the pattern of brain changes in the early …

This paper proposes a novel fixed pattern noise (FPN) calibration technique for a linear-
logarithmic active pixel sensor (APS) based on the conventional four-transistor pixel …

Methods of performing two point calibration of a linear logarithmic image sensor pixel
include measuring Voltages of a floating diffusion region of the pixel after establishing a …

This paper presents a novel rearrangement in an APS pixel architecture that reduces the
number of metal connections delivered to the pixel. Employing four instead of five different …

Methods of calibrating a linear-logarithmic image sensor pixel include performing a reset of
the pixel in advance of establishing a leakage current between a photodiode and a floating …
