    • A solid-state imaging apparatus includes: a plurality of pixels arranged in a matrix; a plurality of amplifier circuits each arranged correspondingly to each of columns of the pixels, for amplifying a signal from the pixel; and a current source transistor whose source is supplied with a power source voltage and which supplies the amplifier circuit with a bias current. When the current source transistor is operating in the saturation region, the gate voltage of the current source transistor that is supplied from the bias line is sampled and held. The gate voltage of the current source transistor with respect to the power source voltage is controlled to the sampled voltage, thereby suppressing variation. This suppression can, in turn, suppress occurrence of line noise and a lateral smear due to difference of drop in voltage of a power source line concerning a column circuit on each row.
    • 固态成像装置包括:以矩阵排列的多个像素; 多个放大器电路,每个放大器电路分别对应于每个像素列排列,用于放大来自像素的信号; 以及电流源晶体管,其源极被提供有电源电压并且向放大器电路提供偏置电流。 当电流源晶体管工作在饱和区域时,从偏置线提供的电流源晶体管的栅极电压被采样和保持。 电流源晶体管相对于电源电压的栅极电压被控制为采样电压,从而抑制变化。 这样抑制可以抑制线路噪声的发生和由于与每行上的列电路有关的电源线的电压下降的差异引起的横向拖尾。
