Abstract
PURPOSE: To reduce KTC noise by sweeping out carriers from a potential well by sensing the threshold of carriers of a second conductivity stored in the potential well in response to incident light and applying a prescribed pulse upon a gate conductor. CONSTITUTION: When light 90 enters, the holes 94 generated in a depletion area at a distance Xd1 gather together in a potential well 100. The space charges stored in the well 100 substantially change the potential distribution. Since a probing current flows to a drain from a source, the number of electrons in an N-channel 102 is kept constant and, therefore, added hole charges are not made up. The quasi-Fermi level 88 of electrons successively shifts after potential change. When a threshold voltage difference is sensed, the holes 94 stored in the well 100 move to a non-depleted substrate by pulsing a transistor gate with a positive voltage and the well 100 becomes empty. After the stored charges are transferred to the substrate, an element becomes ready to store a new group of hole charges.
