ABSTRACT:
This invention relates to an area imaging device having an array of picture elements formed of photodiodes and insulated-gate MOSTs which is vertically scanned by a shift register and horizontally scanned by a charge transfer device (CTD). The solid-state imaging device according to this invention has a transfer MOST provided between a vertical signal output line and a horizontal switch MOST, a resetting MOST connected to the junction between said transfer MOST and the horizontal switch MOST, and a mechanism for setting the vertical signal line at a reference potential just before signal transfer. The transfer MOST connected between the junction of the horizontal switch MOST and the resetting MOST and the vertical signal line is a double-gate MOST formed of a series connection of a transfer gate and another transfer gate. Therefore, the charges under the gate of the transfer MOST can be removed for fixed noise to be greatly reduced.
