Abstract
An image sensor and pixel circuit therefor includes a photoelectric conversion device; an amplifier including a first input terminal connected to the photoelectric conversion device, and an output terminal; a capacitor disposed between the first input terminal and the output terminal; and a reset switch network disposed between the first input terminal and the output terminal in parallel with the capacitor, the reset switch network including at least a first reset transistor, a second reset transistor, and a third reset transistor.
Claims20
A pixel circuit, comprising:
- a photoelectric conversion device;
- an amplifier including a first input terminal connected to the photoelectric conversion device, and an output terminal;
- a capacitor disposed between the first input terminal and the output terminal;
- and
- a reset switch network disposed between the first input terminal and the output terminal in parallel with the capacitor, the reset switch network including at least a first reset transistor, a second reset transistor, and a third reset transistor.
An image sensor comprising:
- a pixel circuit configured to generate a pixel signal, the pixel circuit including:
- a photoelectric conversion device,
- an amplifier including a first input terminal connected to the photoelectric conversion device, and an output terminal,
- a capacitor disposed between the first input terminal and the output terminal, and
- a reset switch network disposed between the first input terminal and the output terminal in parallel with the capacitor, the reset switch network including at least a first reset transistor, a second reset transistor, and a third reset transistor;
- a vertical signal line configured to convey the pixel signal from the pixel circuit;
- and
- signal processing circuitry configured to receive the pixel signal via the vertical signal and to perform at least one signal processing operation on the pixel signal.
