Paper Abstract

This paper presents a solid state image sensor intended for use in 625 lines color TV cameras. The "Line Transfer" organization allowed, using 3 p, design rules over a 6,6 x 8,8 mm format, the realization of an imager whose main performances are : 576 lines by 462 pel, minimum Scene illumination : 30 lux and good protection against smearing and blooming The line transfer organization uses conductive buses to transfer photoelectric information in the vertical direction. The interesting feature of this organization is its ability to separate the signal charges from the spurious ones through a double reading of the bus voltage. The principle of operation and specific performances are first described and expressed in terms of vertical transfer inefficiency. The mechanism of transfer inefficiency is analyzed. Its application to the bus's reading of a line transfer imager is detailed and the main performances are deduced.
