Beschreibung
Zusammenfassung:	A pixel includes a photo-diode, an integration capacitor arranged to receive a photo current from the photo-diode and to store charge developed from the photo current; and an injection transistor disposed between the photo-diode and the integration capacitor that controls flow of the photo current from the photo-diode to the integration capacitor, the injection transistor having a gate, a source electrically coupled to the photo-diode at a first node, and a drain electrically coupled to the integration capacitor. The injection transistor is a silicon-oxide-nitride-oxide-silicon (SONOS) FET having its gate set to a SONOS gate voltage to control a detector bias voltage of the photo-diode at the first node.
