Abstract: A circuit for correlated double sampling is disclosed. In one aspect, the circuit comprises a reset switch connected with an input node, and with a first node of a first capacitor; a sampling switch connected with the input node, and with a first node of a second capacitor; a second node of the first/second capacitor is adapted to be connected with a first/second reference node, of which at least one using a reference switch; a first switch connected between the second node of the first capacitor and the first node of the second capacitor; a second switch connected between the first node of the first capacitor and the second node of the second capacitor.

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.
