摘要： 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.
