摘要： A CMOS sensor has unit pixels each structured by a light receiving element and three transistors, to prevent against the phenomenon of saturation shading and the reduction of dynamic range. The transition time (fall time), in switching off the voltage on a drain line shared in all pixels, is given longer than the transition time in turning of any of the reset line and the transfer line. For this reason, the transistor constituting a DRN drive buffer is made proper in its W/L ratio. Meanwhile, a control resistance or current source is inserted on a line to the GND, to make proper the operation current during driving. This reduces saturation shading amount. By making a reset transistor in a depression type, the leak current to a floating diffusion is suppressed to broaden the dynamic range.
摘要翻译： CMOS传感器具有由光接收元件和三个晶体管构成的单位像素，以防止饱和阴影现象和动态范围的减小。在关闭所有像素中共享的漏极线上的电压时，转换时间（下降时间）的长度大于转动任何复位线和传输线的转换时间。因此，构成DRN驱动缓冲器的晶体管的W / L比是合适的。同时，将控制电阻或电流源插入到GND的一条线上，以使驱动期间的操作电流正确。这样可以减少饱和度遮蔽量。通过使抑制型复位晶体管成为抑制浮动扩散的漏电流，扩大动态范围。

摘要： In realizing an entire-screen simultaneous shutter function using a solid-state imaging device having a device structure as a CMOS solid-state imaging device, the restriction undergone by exposure time is relieved to secure a sufficient exposure time with swift operation. Separately from a transfer Tr for transferring a signal charge of a buried-type PD to an FD, a drain Tr is provided to exclude a signal charge of the buried PD. Both a channel potential on the drain transistor when turned on and a channel potential on the transfer transistor when turned on are set higher than a depleting potential for the PD. This makes it possible to completely transfer the signal charge of the PD by both the transfer Tr and the drain Tr. In the operation to sequentially read out a signal charge from the FD on a pixel-row basis, PD exposure operation is started in a course of reading out the same.
