Claim 13:
14. An imaging device, comprising:
a first substrate including:
a plurality of pixels including a first pixel that includes a first conversion element, and
a first part of a differential amplifier circuit coupled to the first conversion element via a transfer transistor, a floating diffusion and a capacitor; and
a second substrate laminated to the first substrate, the second substrate including:
a second part of the differential amplifier circuit coupled to the first part of the differential amplifier circuit;
wherein the first part of the differential amplifier circuit and the second part of the differential amplifier circuit are electrically connected by a metal bonding,
the capacitor is coupled in series between the floating diffusion and a first input of the first part of the differential amplifier circuit, and
a feedback transistor is coupled to the first input of the first part of the differential amplifier circuit.
