摘要： A row driver assembly includes a row driver unit. The row driver unit includes a buffer circuit that drives a control signal to a pixel circuit. The buffer circuit is electrically connected to a high buffer supply voltage and to a low buffer supply voltage. A voltage converter circuit supplies the low buffer supply voltage to the buffer circuit. An error detection circuit outputs an active error signal when the low buffer supply voltage is outside a target voltage window.

The solid-state imaging device includes a plurality of pixels arranged in a matrix, and each of the plurality of pixels includes: a photoelectric conversion unit configured to photoelectrically convert incident light; a floating diffusion portion in which signal charge generated by the photoelectric conversion unit is stored; an amplification transistor configured to amplify a potential corresponding to an amount the signal charge stored in the floating diffusion portion, and output a pixel signal corresponding to the amplified potential; and a conversion-efficiency adjustment transistor configured to adjust a conversion efficiency of the signal charge stored in the floating diffusion portion. At least a part of the plurality of pixels forms sharing pixels, and a transistor other than the amplification transistor and the conversion-efficiency adjustment transistor is shared by a plurality of pixels forming the sharing pixels.

摘要： Effective pixels and a failure detection pixel are connected to a control signal line for controlling an operation of the pixels and to an output signal line for outputting a result of failure detection in the pixels. Among the effective pixels, the effective pixels in a same row are connected in common to a same control signal line, and the effective pixels in a same column are connected in common to a same output signal line. The failure detection pixel is connected in common to at least one of the control signal line or the output signal line and configured to detect a failure in any of the effective pixels connected to the at least one of the control signal line or the output signal line.
