Abstract
In various embodiments, methods and related apparatuses for scaling down pixel sizes in quantum film-based image sensors are disclosed. In one embodiment, an image sensor circuit is disclosed that includes circuit includes an optically sensitive layer, a first pixel having a first electrode coupled to a first region of optically sensitive layer, a second pixel having a second electrode coupled to a second region of optically sensitive layer, and a readout circuit having at least one transistor that is shared among the first pixel and the second pixel. In a first time interval, the transistor is used in a readout of a signal related to illumination of the first pixel over an integration period. During a second time interval, the transistor is used in a readout of a signal related to illumination of the second pixel over an integration pixel. The signals thusly read constitute a time-domain multiplexed (TDM) signal.
