Abstract
Embodiments of pixel circuit, image sensor, image pickup device and methods for using the same are provided. In an example, the pixel circuit comprises a source module configured to output non-simultaneously a reference signal indicative of a reset level and an electrical signal indicative of incident light, a sampling module comprising a first sampling unit, a second sampling unit and a sampling switch, a first switch module configured to be electrically coupled between the source module and the sampling module, and a second switch module configured to be electrically coupled between the sampling module and a bus.
