Abstract
Imaging apparatus () includes a photosensitive medium () and a bias electrode (), which is at least partially transparent, overlying the photosensitive medium. An array of pixel circuits () is formed on a semiconductor substrate (). Each pixel circuit includes a pixel electrode () coupled to collect the charge carriers from the photosensitive medium; a readout circuit () configured to output a signal indicative of a quantity of the charge carriers collected by the pixel electrode; a skimming gate () coupled between the pixel electrode and the readout circuit; and a shutter gate () coupled in parallel with the skimming gate between a node () in the pixel circuit and a sink site. The shutter gate and the skimming gate are opened sequentially in each of a sequence of image frames so as to apply a global shutter to the array and then to read out the collected charge carriers via the skimming gate to the readout circuit.
