Abstract: A photoelectric conversion apparatus comprising: pixels; processors; and a controller. Each of the processors comprise a first column circuit and a second column circuit, each of which perform A/D conversion of converting, into a digital signal, one pixel signal output from the pixel arranged in a corresponding column of the plurality of columns. The controller comprises a generator configured to generate a first signal used in the A/D conversion, and a second signal different from the first signal and used in the A/D conversion. The apparatus further comprises a selector configured to receive the first signal and the second signal, and select and supply one of the first signal and the second signal to the second column circuit in a period in which the first signal is supplied to the first column circuit.

Abstract: A photoelectric conversion apparatus comprises a first substrate having a light-receiving array and a plurality of driving lines for supplying control signals to the array and a second substrate having a first circuit that includes a driver circuit group configured to generate the control signals and is configured to function as a vertical scanning circuit which supplies the control signals to at least some of the driving lines and a second circuit including a circuit group having the same arrangement as that of the driver circuit group. The second circuit overlaps the at least some driving lines. The at least some driving lines include a driving line not electrically connected to the second circuit. The second substrate includes, at a position overlapping the second circuit, an electrically conductive line used for power supply or transfer of a signal different from the control signals.

Abstract: A photoelectric conversion device comprising: a pixel signal line configured to transmit a pixel signal; a ramp wire configured to transmit a ramp signal; a comparator configured to compare the pixel signal to the ramp signal; and a capacitive element disposed to have at least a part thereof overlapping the ramp wire in plan view.

Abstract: Provided is a signal processing device including a first substrate, a signal generation circuit arranged in the first substrate and configured to generate a reference signal to be used for comparison with a signal output from a pixel, a circuit element arranged in the first substrate and different from the signal generation circuit, and a contact region in which a contact connecting the first substrate and a wiring layer arranged over the first substrate is arranged. In a plan view with respect to the first substrate, the contact region is arranged between the signal generation circuit and the circuit element.
