Image capturing that suppresses a drop in numerical aperture and achieves a smaller size is disclosed. In one example, an image capturing apparatus includes pixels each having a photoelectric conversion unit, a floating diffusion that outputs a voltage according to a charge obtained from photoelectric conversion by the photoelectric conversion unit, and a current amplification unit that amplifies a current according to the voltage of the floating diffusion. The region in which the photoelectric conversion units are disposed and the region in which the current amplification units are disposed transmit and receive the voltages of the floating diffusions through a corresponding signal transmission unit.

Image capturing apparatus and electronic device

A comparator includes: a first amplifying unit that includes a differential pair configured with a pair of transistors which are first and second transistors, and amplifies a difference of signals input to each of the gate electrodes of the first and second transistors, to output; a second amplifying unit that amplifies the signal output from the first amplifying unit; a third transistor that connects the first transistor to a power source voltage; a fourth transistor that connects the second transistor to the power source voltage; a fifth transistor that connects a connection point of gate electrodes of the third transistor and the fourth transistor to a drain of the third transistor; and a sixth transistor that connects a connection point of gate electrodes of the third transistor and the fourth transistor to a drain of the fourth transistor.

Comparator, solid-state imaging device, electronic apparatus, and driving method

There is provided a solid state imaging apparatus, including a plurality of line sensors including a plurality of pixels arrayed in a line, each of the pixels including an amplifier which amplifies a signal corresponding to a charge accumulated in a photoelectric transducer, and signal lines each for reading a signal of each pixel of the line sensors. The plurality of line sensors are discretely arranged, and the signal lines are gathered and wired along a region in which a circuit block including the line sensors is arranged.

Solid state imaging apparatus, electronic apparatus, and pixel reading method

A solid-state image capture device includes unit pixels including transfer gates that transfer charges to diffusion layers, the charges being obtained by photoelectric conversion performed by photoelectric converting sections; signal lines to which signals output from the unit pixels are read out: current sources connected to the signal lines; and a driver that electrically cuts off connections between the unit pixels and the signal lines and the signal lines and the current sources in a transfer period of the transfer gates.

Solid-state image capture device, drive method therefor, and electronic apparatus

A comparator includes: a first amplifying unit that includes a differential pair configured with a pair of transistors which are first and second transistors, and amplifies a difference of signals input to each of the gate electrodes of the first and second transistors, to output; a second amplifying unit that amplifies the signal output from the first amplifying unit; a first condenser that is disposed between a gate electrode of the first transistor and a reference signal supply unit; a second condenser that is disposed between a gate electrode of the second transistor and a pixel signal wiring; a third transistor that connects a connection point of the gate electrode of the first transistor and the first condenser to the pixel signal wiring; and a fourth transistor that connects a connection point of the gate electrode of the second transistor and the second condenser to the pixel signal wiring.
