Imaging apparatus
Provided is an imaging apparatus including an imaging unit having a plurality of pixels, the pixels each having: a conversion element converting incident light into photoelectrons; a floating diffusion layer electrically connected to the conversion element and converting the photoelectrons into a voltage signal; a differential amplifier circuit electrically connected to the floating diffusion layer, including an amplifier transistor to which a potential of the floating diffusion layer is input, and amplifying the potential of the floating diffusion layer; a feedback transistor electrically connected to the amplifier transistor and initializing the differential amplifier circuit; a clamp capacitance connected in series between the floating diffusion layer and the amplifier transistor; and a reset transistor connected in parallel between the floating diffusion layer and the clamp capacitance and initializing the potential of the floating diffusion layer.
