Abstract
A pixel for converting incident subatomic particles into an output voltage signal is disclosed. In one aspect, the pixel includes a photo-detector adapted to receive incident subatomic particles and generate an input voltage signal corresponding to an intensity of the received particles. The pixel also includes a passive amplifier adapted to passively amplify the input voltage signal to generate an output voltage signal. The passive amplification reduces the noise of the output voltage signal, and may have a higher quantum efficiency than typical in-pixel amplification devices and methods.
