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.

摘要： In an A/D converter, a first analog signal which is input to an input terminal in a state in which the input terminal and a reference voltage line are connected via a first capacitor is converted into digital data when a reference signal is supplied to the reference signal line in a state in which the reference signal line and a first input terminal of a comparator are connected via the first capacitor. A second analog signal which is input to the input terminal in a state in which the input terminal and the reference voltage line are connected via a second capacitor is converted into digital data when the reference signal is supplied to the reference signal line in a state in which the reference signal line and the first input terminal of the comparator are connected via the second capacitor.
